Add two shortcuts to command MS 4 nightly

OS: Linux Mint 20.3, Arch.: x86_64, MuseScore version (64-bit): 4.0.0-3034716910, revision: 5377cef

I would like to assign two different keys to a command in the shortcuts. One on the normal keyboard, one on the numeric keypad. Is that possible? In my efforts I could only assign one key.
Greetings and thank you for the coming version 4,
