Own Console Version, considering purchasing PC version question

I currently own the ps5 version of the game with all of the expansions. I recently bought a gaming laptop to travel with so i am considering purchasing the pc version of d4 with all of the expansions.

I have my battle net account linked already for d2r crossplay between ps5 and pc.

I currently have 16 character slots on ps5 with the 2 additional slots from the prepurchase of the expansion. If i purchase the pc full version and expansion what will the number of character slots be? Will the +2 character slots from the pc prepurchase add 2 more on the ps5 due to the linked account or will it stay 16 on ps5?

Thanks

from what i’ve observed the additional prepurchase slots don’t stack, keeping the 16 slots on both. also just as a heads up if you bought the premium edition of the game/expansion pack on console/pc you already get the cosmetics on the other platforms even if you buy the standard version.
