Renaming SharePoint 2010 Designer Approval Process Action Variable Name

Question

Hi,
I am creating a 7 level(Mutiple) Approval Workflow in SharePoint 2010 Designer.
Whenever i add a new Approval Task Process action it adds 14 to 15 varialbes like Duration Unit,Duration Description,IsApproved,IsDeleted,EnableContentTypeApproval etc.
Since i am adding 7 Approval Task Process actions i am getting the variables added as Duration Unit1,Duration Description1,IsApproved1,IsDeleted1 etc in the Workflow.
I want to rename them to track it  in a better way so that i can change them like Duration Units-Level1,Duration Description-Level1,IsApproved-Level1,IsDeleted-Level1 etc.
I am able to rename all the varaibles except Duration Unit and Duration Description. I see the Local varaible type as Duration Unit for Duration Unit varialbe and i am not able to modify it since i don't see a Type Called Duration Unit in Workflow variables
type properties.
For Duration Description i can rename it but while publishing i am getting the error as mentioned in the below blog.
http://spnovice.blogspot.com/2012/12/spd-workflow-error-path-needs-to-point.html
It's hard to track this varible with names like Duration Description,Duration Description 1,Duration Description2,Duration Description3,Duration Description4,Duration Description5,Duration Description6 etc.
How to rename these two variables in Approval 2010 Designer workflow.
I see varailbes like CC and Approvers which i dont need.Can we remove the unused vaiables also so that i can have limited no of vaaibles in my workflow.
Please help.

Scott,
I have created 7 different approval workflows on a single list.Just followed the recommendation from
Keith Hudson, J.D in this blog.
https://www.linkedin.com/groups/sharePoint-designer-2010-multilevel-approval-136589.S.5824115633184350208
But as per this blog the workflows triggers only when a new item is created not when a an item is changed.
I have few questions on these 7 workflows on a single list.
1.If the Approver rejects the request the request needs to reubmit it with some changes.In this case if the requestor edits the existing list item the workflow will not trigger.
2.I am using Wait on Field action.For Example if Level 1=Approved and Level 3 is pending then level 2 approval workflow will trigger.
In level 2 workflow i am using  update list item  action and updating the Level status=approved.Int this case level 1 workflow will also trigger if i am executing the workflow on both item created and item changed event.
Could you please help on this.
