Can EPM be used to provision more than 8 accounts per device?

FreePBX 14.0.17

I’m trying to use EPM to provision some grandstream gateway units that have 16, 24 & 48 ports but currently I’m only able to assign 8 extension to each device. I though I remember being able to fully provision these device before but now I can’t figure out how to utilize more than 8 accounts.
Using the brand Grandstream and the model GXW-4216, 4224 and 4248
