Duplicate assignment in keyboard mode

[tomo39]

When input mode is set to keyboard
The up, down, left, right arrow buttons also move to B1, B2, B3, and B4.
I want to assign duplicates.

If you allocate duplicates
"Key Arrow Up is already assigned" appeared and could not be assigned.
Please let me know if there is a way to assign

I want to enjoy DDR with GP2040 embedded in PS controller

It seems possible to do this by changing the Pin Mapping profile.
I apologize to you for a fuss over
