I wanted to have different hotbars for scholar when I had Selene or Eos out. On my character I reserve three always visible hotbars as job specific, a fourth hotbar across all jobs (for marking, sprinting, and other universal stuff), and use my 9th and 10th hotbars for gearsets.
This leaves hotbars 5, 6, 7, and 8 'free.' So I first made them unshared (job/class specific), then filled 5 and 6 with what I wanted in hotbars 1 and 2 for Eos, and 7 and 8 with what I wanted in hotbars 1 and 2 for Selene. Finally I set up my summoning macros like so:
Eos:
/micon "Summon"
/hotbar copy Scholar 5 Scholar 1
/hotbar copy Scholar 6 Scholar 2
/ac "Summon"
/wait
/pac Obey
Selene:
/micon "Summon"
/hotbar copy Scholar 7 Scholar 1
/hotbar copy Scholar 8 Scholar 2
/ac "Summon"
/wait
/pac Obey
