Can you force an ARS workflow based on a change to run on a specific admin server?

I'm using the handle changes from dir sync control feature of provisioning policies to update a virtual attribute and then using that change to trigger a workflow.

This is all working great.

The issue I am having is since I have 8 ARS admin servers this workflow can be triggered as many as 8 times. I have coded around this problem, but I am trying to figure out how to make this workflow run only once.

I don't see the option to force a workflow to run on a specific admin server, but I thought it might be worth a shot to ask.
