How to conditionally supress accounting entries in case of transfer of items between inventory orgs

Summary:

We have a single Cost book, Single Cost org , Single BU and multiple inventory orgs associated with the single cost org. We have setup SLA rules to define mapping sets for inventory valuation etc so that appropriate accounts can be used when an item is transferred from one inventory org to another.
The client has a requirement that when an item is transferred from a A org(inventory org) to an A field warehouse (another inventory org), this should be treated as a location transfer and accounting entries should be suppressed (not generated at all) using SLA. However when an item is transferred from a A org to an B (another inventory org), accounting entries should be generated in this case. We are using Perpetual Average costing method.
