What you can do is Pin the products to create a Production Order for into the clipboard.
Then you can start a Production Order and enter the location where production will take place.
Finally, instead of entering one by one the products and quantity to be made you can open the clipboard and click Paste.
This will create all the relevant Production Orders in a single click.
These orders will have a common reference number so that they can be associated among them.
The products in the clipboard to be used in this approach need to be of Product Type 'Manufacture from Production Order' or ''Manufacture from Production Order and Buy from Supplier'
