Remap command with parameters

[CptPotato]

Is it possible to map commands that require additional inputs to a key? I'm thinking of something along these lines:

a = ["find_next_char x"]

I feel like there was an issue related to this, but wasn't able to find one.

I think this needs pr #4709

Thanks, this is exactly what I was looking for.
