Does anyone know if its possible to change the prepayment account manually from the drop down on each vendor prepayment you do? Our is blanked out and the field display type is set to disabled

In the upcoming 2021.1 you can now have multiple vendor prepayment accounts I believe. For now we're limited to one.

Ok, I have tried using this feature on the release preview but without any luck. Has anyone used it successfully in the release preview, where they could change the vendor prepayment account?
