Tried as well. No luck. I put in a feature request for this, so fingers crossed.
For those seeing currency editor issues (i.e you see '1' no matter what) - it seems the game differs in addressing for this between DX11 and DX12 (running in DX12 fixed it for me)

Does anyone have a savegame where we can easily access the prestige XP and see if we can do something with it?
Where is Prestige XP?
