How do I get the row number in a multirow variable set in a Flow For Each loop?

[gjz]

I have a catalog item that uses a multirow variable set that allows the requestor to add up to 25 volunteers who need an Active Directory account.  It currently uses workflow.  In the workflow, there is a Parallel Flow Launcher step that calls another workflow and processes each volunteer.  I need to convert the workflows to a flow, but I'm really stuck on processing each individual separately since I can't find a way to get the row number in the For Each loop.  Does anyone know how to get the row number? Or a better way to convert the workflow to a flow with the same requirement?

@gjz You can define a flow variable and increment it with each loop iteration.

Hope this helps.
