HDL to end date offer assignment

We have a scenario where a candidate applied as external and offer was created, then it was determined that the profile needed to be merged. The profile was merged with Contingent worker and attempting to draft and offer on a new requisition, however the correct action reason is not present because the existing offer is still present even though application has been deleted.

Is anyone aware of a way to end the current offer assignment (likely to update the active flag or assignment status) through HDL or another method so that it isnt blocking the new offer from being created accurately?
