I am working on a new workflow that would do this.
when a person creates an epic and utilizes a certain word - decom
that the workflow would create the epic and 1 story assigned to a dept to process (i have that working).
once that team has closed it, then it would then create another story and keep it assigned to that same epic.
This could happen multiple times depending on the decom ticket and which teams need to process a removal of an item.
This needs to be done in order as if anyone rejects, than the process would stop. but also, the process has to be done in order or alarms go off.
