Create a view - All Service Requests that contain a Completed Review Activity

Question

In the Service Manager 2012 console, is it possible to create a view that displays Service Requests, with the view criteria being something like as follows:
Service Request status is In Progress
Service Request contains a Review Activity where the Review Activity status is In Progress
My intent is to provide a way for Service Desk Operators to be able to identify requests that are ready for implementation.
From what I'm seeing in the console, this sort of view is not possible as it appears that any view criteria must be derived from the view's target class.

Nothing like a bit of thread necromancy in the morning.
It turns out the solution to this question was quite straight forward (once you know where to look...)
The trick is creating a view based on one of the Service Request combination classes rather than the basic class itself, and then rephrasing my requirement after realising that what I was really after was a view containing Requests that have an In Progress
Manual Activity.
So...open the console, go to Work Items, right click on
Service Request Fulfillment and select Create View
On the General tab, give your view a name and select a Management in which it will be stored.
On the Criteria tab, click Browse to select a specific object class.  Change the
Frequently used basic classes filter to Combination classes then enter 'Service Request' in the filter field.
Pick the Service Request and Activity class.
Now when configuring the criteria, you'll notice a little arrow next to the
Service Request class. Click on this arrow to expand the node, and select the
Contains Activity class.
Under the Available properties box, enter 'Status' in the search field. In my environment, I got two Status fields. Each corresponds to a specific Activity class. Select both of them and click
Add.
One of the Criteria will look like 'Contains Activity[Activity]Status'. Keep this one and delete the other from the Criteria box. Change the value to 'Completed'
While we're at it, select the Service Request class and add a criteria for the Service Request Status = 'In Progress'.
Click on the Display tab and select whatever fields you want to display in this view.  Click
OK to save this view.
Now go to the Administration workspace and select the
Management Packs node. Export your management pack that contains your view and open the management pack in a text file viewer. Notepad++ works for me...
First search for the string that you used to name your view. It will be found towards the bottom of the MP in a DisplayString element in the LanguagePacks XML element. This element will have an ElementID.
Select the ElementID and search the entire file for this string. You want the instance that resides within a Presentation | Views | View element. From this point, scroll down until you get to a Criteria element. Within the Criteria element you will find
the two Expressions that were entered via the GUI. One of the Expressions corresponds to the Service Request.Status=In Progress criteria, the other corresponds to the Activity.Status=In Progress criteria. We will be changing the Activity criteria so that it
explicitly refers to a Manual Activity.
Identify the Expression that has the Property containing the string 'System.WorkItemContainsActivity'. We will be changing the TypeConstraint attribute of this criteria.
In this line, Replace the string 'System.WorkItem.Activity' with 'System.WorkItem.Activity.ManualActivity'
Save this file and import the management pack into SCSM
