Canon R5 II Customised Buttons

[MrSparks999]

I use the C1, C2 and C3 on my R5 MKii for different scenarios. My question is this:
If i customise a button does that carry across to C1,2 and 3 or do i need to set up specifically for each one?

So example, if i switch to manual mode and customise a button, does that button remain customised if i then switch to C1, 2 or 3?

Thanks in Advance.
