Ah I see, definitely better if you can double up.
I had this same issue when I was doing wedding invites for a friend that were 12” high in total.
What I ended up doing was making an alignment jig, doing the bottom half of multiple pieces, then rotating it to do the top halves. Worked really well.
I wrote a post about it on here a long time ago. I think it was titled “batch production using a jig” or something along those lines
Edit - here it is: Tutorial - Batch Production With a Jig
