Instead of having one line of post function to "copy field value to Parent" issue, I really, really REALLY want a Scripted Function that reads custom fields on a sub-task for change, and if changed carries that value over to the parent. I cannot figure out how to do this.
This would save us countless errors in accuracy (fields not being added to older workflows) not to mention hours of recreating our workflows when we merge our current instance into our goal instance.
Gratuitous Math: We have 20 workflows with about 10-15 steps each, and around 136 custom fields - we have an average of 55 applicable to each workflow step transition, of which there are an average of 4. 20*10=200 transitions. 55*(10*4)=2200 custom field lines. 200*2200=44,0000 lines to write back in for all transitions.
