Item template question - Setup all item to the same Item Subinventories

Hello gurus,

all our items are going to the same Item Subinventories and locators. Is there a way to include these Item on the Copy from Template we are using, instead of manually assigning items to their subinventory and locators one by one? Or is there a Standard Mass Load available for assigning Item Subinventories?

Also, we are looking for a Standard Mass tool program to Inactive many thousdands of Items. I would like to use a standard program instead of using the update script to Mtl_system_items.

Please let me know if you have suggestions.

Thanks a lot
