There are two sub-cases ,let's say subCase_1 and subCase_2 and we have a local action of an assignment in subcase_1 to update the certain details which triggers to route the subcase_2 to different workbasket .

I tried to use ReAssign/pxTransferAssignment but the challenge is, there is no provision to pass assign page explicitly to OOTB reassign utilities as both of them are defined with newAssignPage to process the task routing. if I use OOTB routing utilities then the current assign page gets overridden once the local action of assignment is submitted.

Any better approach to handle this usecase without having customized version of reassign activity..
