Hotspot & PPPoE on the same router ?

Can we have hotspot and PPPoE customers on the same router ?
Is it possible ?

And we recently started our WISP and we are using Hotspot.
We use CCR1009.

The bandwidth manager, which we are using, its developer says, Microtik Hotspot has a limitation of 200 online users only.
I was shocked to hear this!!
Is it true ?

And if its true, then is there a one click method or easier method to change all the customers from hotspot to PPPoE without going to them individually ?
