Possible to combine accounts?

I was wanting to play on PS5/PC so I got a free invite (PC) and I purchased a invite (PS5).

Was hoping to hop back and forth/play with the wife.

I successfully created and linked my PS5.

With that said, I have to swap to my PS5 account to be able to use my Characters. I also can't use my PS5 account on a PC as it keeps my purchases (on PC) on a separate PC account) IT does not make them remove only, it makes them whole separate accounts. Is there a way to combine accounts? Is there a way to log onto the PS5 Using my original account?

Is there a way to convert PS points on one account and send them to the other so I don't have to jump accounts/purchases?

I can't use previous purchases (from poe1) while I am playing on PC... IF i want to use the characters I got on PS5?

IF none of this is possible, can I just refund/delete the PS5 account and have the $30, added for a PC purchase? I have not spent any of the 300 coins given.

I do get the ability to talk to myself though...

This is the PS5 Account, linked yet I can't use PC purchases on it (even on PC).
