Easier way to book things into stock in the correct location on Purchase Orders

We'd like it to display the locations assigned to the products In a simple drop down or similar on purchase orders on desktop much like on the mobile app where you can only select available locations or type to add a new one. We think at least until the IOS app is available this is really needed as not everyone in the work place necessarily knows the name of every location, not everyone has an android phone and mistakes happen and booking into the wrong location can be quite annoying and time wasting. I also thought I might as well throw this in the mix as there is also an issue where when booking in a purchase order that is more than 1 page, you fill in all the information on the first page and then press the next page button, it doesn't save the data you input to the first page and you have to restart, not the biggest problem but again annoying when it happens and time consuming. Example: On desktop, the purchase orders page should work like it does on mobile; where you click the location box, the available locations appear and you select the one you want. If it's a new product still keep the option to type in the location manually in case it's new or doesn't have the location you need assigned to it already. Basically make it like the mobile app and easy for anyone to book in stock to the correct place.
