Is it possible to make changes to Supplier's tab of released items without having to roll rev?

We want to manage the Company's Approved Suppliers List (ASL) using the Suppliers tab on the Parts but we are concerned that adding a Supplier or removing a Supplier requires an ECO thus a Revision Roll.  Can I resolve the rev roll requirement with roles and privileges or is this inbuilt functionality.  We currently use Mfrs Tab to mange the Approved Manufacturers List (AML) and we be OK if Suppliers Tab changes could be managed with MCO.  We are not using the Suppliers Tab for the Costing Module functionality it be simply for ASL management.

Any guidance is much appreciated.
