Help with Switching Playtest Platform

Hello, I recently received access to the FC 27 playtest, and I’m really excited to have the opportunity to try it out. Unfortunately, my PS5 is currently being repaired under warranty, and I’ve been told that it won’t be back with me for at least another two weeks.
I also own FC 26 on both PC and PS5, but I’ve mainly been playing on PC recently, as that’s the platform I prefer to play on.
I contacted support to ask if it would be possible to switch my playtest access from PS5 to PC, but they suggested that I post my request here on the forum.
I completely understand if this isn’t something that can be changed, but if there is any possibility of moving my playtest access to PC, I would really appreciate it. I’d genuinely love to be able to take part in the playtest while I have access to it.
Thank you very much for taking the time to read this, and I really appreciate any help you can provide.
