EBS Payables Pay Groups - Using the tag field

Like most Oracle EBS instances we have multiple businesses on the same instance across the world. In Payables we have multiple Pay Groups set up for the various types of payment for each of our entities.

My users want to be able to run a report of all the suppliers in their pay groups however they only want to be able to select from their pay groups. I was thinking of using the Tag field within the Pay Group table, populating this with an identifier and then getting the report parameter to run off this.

Has anyone done this and will i course a massive meltdown if I do??
