hey i was wondering if any one knew how to link warehouse internal locations that i already created to Products and Product Variants?

 If i have to utilize studio to do that what models' and fields do i use? 

Plus how do i ensure the pathways are correct causes i run a rental business for events, so i do not sell products i send them out and bring them back through the week. So i would like to set these locations as the pick and return locations? 

As well another issue i have been facing was i had trouble uploading csv data form my old program. i was able to get to a point to pass the Odoo import test but once i took a look at the import in Odoo it was missing products, did not auto generate barcodes or link to location paths or upload initial stock  ? 

how do i also set up auto barcodes in Odoo 17 all i seen is it for past versions? 

Lastly if i was to utlize the google picture process to get product pictures, how do i go about that as it requires barcode as reference data, is there a standarlize barcode process i need that i also need tell odoo to follow in order to make them understand each other? 

Where a small business and dont have the funds to support integration process from Odoo. so i been trying to learn and do a lot of it myself please support if you know anything. As well i not very IT oriented  i come from a data management background in warehouses sector, so i know how to run a prebuilt system never set one up.

 Once again thank you for the support
