Suppose we have a parent case A-1 and we created a child case B-1, there is requirement in which for a particular scenario they want the child case B-1 to be moved to another top level case C-1. 

can we configure this in Pega? 

for example

Parent : A-1

Child : B-1

another Top level case without any child currently : C-1

**call some logic** and the expected outcome should be as following:

Parent : C-1

Child : B-1

Case without any child : A-1

What I suggested is create another case B-2 and copy all the data from B-1 but they want to retain the case id for some reasons.
