Pair the 8 outs for stereo (MPC 2500 JJOS 2XL)

I remember I could pair two of the separate outs on my 2000XL to get stereo, assigning a stereo sample to 1/2 or 3/4 for example.

But I cant figure out how to do this on my 2500? I have a stereo sample that I want to assign to a paired separate output but I can only assign it to a mono separate output it seems. Im sure you can do what I want so I need help to figure it out!

Thanks!

I don't know about 2500 but this option exists on 1000 with XLOS. It's in program menu in OUT tab, and than in OUT column there are all options you want.
