We fulfill for many stores through Printify. Many of the stores we fulfill for want their own address for the return address. After a couple of years doing this our ship from locations, 'warehouses' in the API, have become bloated to the point web browsers and api scripts are having real trouble working with ShipStation. On the UI side, we can only delete these one at a time. On the API side, we can delete in bulk, but we can't tell which are actively used. There is a create date, but this doesn't tell us which locations are still associated with recent orders.
It would be great if:
ship from locations could be deleted in bulk through the UI
ship from locations would store the date of the last order that used it.
These would be great features for any fulfillment house shipping for many client stores.
