Hey guys, is it possible to do this, we want to only enable branded shopping but disable branded search with Pmax?

Hey guys, in the Youtube video Complete Performance Max Campaigns it's mentioned to split out best sellers into there own campaign, if you have a store of 2000 products what is a good way to do this? As products can also change from best sellers, to mid-tier, and zombies. How do you continously monitor this and ensure the products you have allocation to each campaign correct?
