We have around 2000 products in Odoo16. Now, after two years using ODOO, we want to start working with POS.

a) At the moment none of the products are "available in POS".

b) Not all products should be "available in POS".

I am looking for an effective way so that I don't have to go through all 2000 products individually to activate the "AVAILABLE IN POS" checkbox one by one!

c) How can I select certain products and activate "Available in POS" with just a few clicks?

d) How can I do c) and then put them in a category straight away? 1. Accessories, 2. Spare parts, 3. Accessory brand, etc.

I can't imagine that there isn't a smart way!?

THX!
