Which column can we use to sort products by last (actual) edit date? (if any)

[the.rampage.rado]

Today I tried making a query that sorts the products by last edit date using date_upd column.

The issue is that this value gets changed even if we save other products in the same category (lets say changing the position in the category).

My use case is that I have couple of categories that I want to manually (i don't have a automatic way to do so) edit (stock and combinations) and I want an option to sort those products so I start from the one that is updated furthest back in time so not to loose hours on repetitive work and (sort of) keep this list of products optimized.

Could there be any workarounds around that?
