Is harp condensing possible

hello everyone, i’m trying to scoring a giant orchestral work, which includes 8 harps. I tried to conde se them but none of the harp are in the “custom condensing group” windows. I wonder if it’s possible to condense harp or other instruments like piano?

Condensing is limited to single staff instruments. That’s why you can’t condense harp or piano.

Possibly teaching you what you already know.

Create a new harp player. Import as many harps as you can/want/make readable to that instrument. Create a new score layout, with the “imported” harps not shown.
