Hi allarmsllc ,
Thank you very much for your reply.
Now I understand what you are talking about. Well it is a little bit more complicated from here and I apologise ahead.
The ability to add one product more than once into the PO was actually a bug not a feature. We have had many users complaing about it so we have fixed it in version 1.9.44.
We know now that 2 users including you took advantage of this bug thinking it is the way it should work. I apologise about that as it was an oversight. The only way you can take advantage is to return back to version 1.9.43.x but then you may experience issues with incompatibility in the future.
The other user that had the same work flow as you decided to use our Multi Inventory premium addon that actually allows him to add more inventories per product and keep even better track.
Once again, I apologise for any inconvenience caused.
Pavel
