Remote desktop using only some monitors (right not left)

I have a Windows 11 workstation with 4 monitors. From left to right they are in order 3,1,2,0 (using mstsc /l). They are all different sizes (see image) but have a shared top.

I want to RDP using only 3 monitors. I have managed to get this working using the left 3 monitors using the paramaters:

use multimon:i:1selectedmonitors:s:3,1,2

However I want to use the right 3 monitors.

I have tried:

selectedmonitors:s:1,2,0

But that doesnt work it tries to put an image the size of the right 3 monitors but starting with the 1st Monitor.

Any tips how to do this?
