Selecting multiple expansion patches in one performance on Roland XV-3080

Hello,

I've been trying to set up performances on my 3080 which are made up of several patches from SR expansion boards (specifically Dance and Vintage), but keep finding that I am not allowed to choose multiple sounds from the same card on the synth and on PC editor. I am slightly puzzled as my JV-1080 allows me to do this.

Is there any way that I can use multiple patches in one performance, or is it a hardware/firmware thing?

On a slightly different note, I'm considering upgrading it to an XV-5080 (for the bigger screen); does anyone know if this can access multiple patches simultaneously?
