Dynamic PPR in ADF Tree

Question

Is it possible to dynamically add a partial target to be rendered in the subsequent response in ADF Tree?
Say for example I have a tree as follows:
Root
- Child 1
- Child 1.1
- Child 1.2
- Child 1.3
- Child 2
- Child 2.1
- Child 2.2
Now I would like to re-render ONLY "Child 2.2" when "Child 1.3" is updated via "autoSubmit" or "f:ajax". Note the knowledge of the "node to be rendered" is not available during design time, i.e. it is only dynamically known when a value is being set in "Child 1.3" or for that fact any other node.
I could bind the component to a UIComponent and then use "context.addPartialTarget(UIComponent)" but the way that I see it, component binding is a view build time process and when the tree nodes are being rendered, it uses the same UIComponent instance to render each of the nodes and would try to fetch each of the visible node and see whether a change has been made and partially render it accordingly on the condition whether it has been changed or not. I need a mechanism in which if I change "Child 1.3" and it specifies to partially re-render "Child 2.2", it shoud ONLY re-render child 2.2 and not any other node whatsoever.
Is this currently possible? Moreover are <f:ajax> and ADF PPR interoperable?

Glad to know the answer. Thank you. :)
Here's a suggestion which is inline with JSF
JSF 2.0 (or was it 1.2) defines PartialViewContext which has it's roots with <f:ajax>. PartialViewContext basically states all the client ID's which will be re-rendered durig this process with a mutable getRenderIds() collection (although it's mutable, it's not specified in the docs whether changing it will lead to actual changing of the list or not. It works for the Mojarra implementation in WLS 12.1 (Mojarra 2.1.5) but was not working in 10.3.5 (Mojarra 2.0.9). In any case I can always override the PartialViewContextFactory to provide a wrapper of PartialViewContext which supports mutating). What I would like to propose is that since I can dynamically state client ID's which needs to be re-rendered, I can state the client ID's of the node components and they be rendered accordingly. This would be very helpful since in our current implementation we were hoping to have a very optimized implementation of af:tree which could be having several nodes and each node can change depending upon a change in any other subsequent node.
I have tried this new method and it works like a charm with other ADF components including components within iterators and switchers, howsoever it failed to work inside a tree. It would actually be a good addition/fix.
Thank you once again.
