Not aware of any add-ons or utilities to do that specifically. If you mark the warehouses as inactive, as long as this option is unchecked for the company, then you won't have them showing up in the lookups.

It does not seem to affect the warehouse quantities displayed in Item Inquiry/Maintenance though.
At one point, I think Scanco may have had a warehouse renumbering utility. Not sure if it is available separately but I recall seeing it on a system with their WMS enhancements. Never used it though so not sure if it could be used to merge the unwanted warehouses into a single warehouse.
