Select warehouses in Production Plan with 'Get Raw Material For Production' issue

How can i add warehouses more effectivly to a production plan for the “Get Raw Material For Production”?

Selecting them one by one is difficult and error brone if one has many warehouses.
Furthermore, the list does not show all the warehouses. Only if i remember the warehouse names and start typing, the missing ones are listed and can get selected.

Only one Warehouse Mxxx listed

If i start typing, i get the missing warehouses listed
