Hi @AdamFromson
I may be misunderstanding the requirement, so apologies in advance, but from the way I’m reading it, this may help:
1. Set up a feeder workflow, that contains a number of if/then branches to check the contact for membership of 3 individual workflows. These if/then steps will then enrol them to the desired workflow, depending on their prior workflow memberships (e.g. #3 if they’ve already been in the other 2).
2. Set up each of your 3 workflows to handle nurturing to the goal submission (you can then name them specifically in the if/then steps of your feeder workflow).
3. Add a final step in each of the 3 goal workflows, to add the contact back into the feeder workflow.
If the contact has completed all 3 workflows, they can either drop out of the feeder workflow (and therefore all workflows), or you can add a step to add them to a newsletter list or other regular comms stream. You could add an internal notification step, if you wish for a human to pick up the trail - whatever your preference.
Does that help?
