Changing room appearance

Hi there,  a little while ago I remember seeing somewhere that you can alter the changing room start screen with the help of a MOD. This may have been for FM19 or 20 but I can’t find it now. 
With the recent revelation of the ability to alter the press / interview boards, does anyone know if this is possible? 
Just little changes like club logo on wall and a few other little amendments would be nice.

Thanks in advance.
