[No DAV spoilers] Selling items to the right faction in Veilguard

So I've seen it mentioned that you can rank up factions faster by selling them thematically associated items. Is there a guide on this yet? How fast can you max out the factions this way? It'd obviously be handy to get to the top tier stock quicker, but if I can max them out either way then I dunno if I'd bother.
