Resuming tree execution

[Alexferlisi]

i am using behaviorTree.CPP library for my project ( versione 3.8) and in particular i am focusing on recovery strategy when the execution fails.
So far, i have a sequence of actions to execute (ex. action2 -> action3 -> action2 -> action3) with different parameters, if the state of the scene is always as "expected" the sequence of action can be executed easily.
now, let's suppose i changed the scene state such that action3 can not be executed because its preconditions are not satisfied, i have implemented a recovery strategy (with a Backup Tree) to bring me back to the "expected" state of the scene (and it works!) such that action3 can now be executed.
So, after that, i would like to resume the MainTree execution from the point where it fails (action3) because i don't want to restart the tree from the beginning, repeating action2 which has been already successful, is it possible to do that?

I hope i was clear explaining my problem. Thanks a lot!
