any way if user take action from VBCS page then PCS workflow need to resume and go for next approval

Summary:

Hi is there any way when a user take action on the VBCS page(approve or reject) then PCS workflow should go for NExt level approval

like for that we have the REST api to get the Task number with process ID we are using integration, but in our case we are using subprocess(parallel subprocess) its generating multiple Task Number for single process ID and our workflow is TWO level approval, at first level we are getting multiple task numbers

so how can i manage that many task numbers to take correct action from VBCS page

like in HUMAN task it is allowing only to get task number in the OUTPUT side but i need to get it when it is assigned in the PCS itself, is there anyway in PCS that i can get the task number
