Based on this I would try to do more but not much more and stick to same compounds at least between sessions so you can more readily gauge when they're prime to add weight.
1x seated cable row
1x lat pull down or whatever variation of pullup
1x hammer curl
1x rear delt fly or rhomboid thing
1x ez bar or straight bar curl
Then tack half your back leg work onto that day
RDL
Hamstring curl
Glute whatever
Back extension
So every group and every head is getting at least 2 sets of quality work a session.
