[cisco-bba] PPPoE and many virtual-templates (per subif/vlan)

I'm using the following config in order to accept and terminate PPPoE connections on a 7200 router.
The 7200 is connected through ATM/ima with a 6015 dslam.

I'm trying to associate PPPoE users to different virtual-templates, based on the atm subif (or maybe 
vlan in the future) on which they are terminated.

!--------------------------------------------------
vpdn-group PPPoE-USERS
  accept-dialin
   protocol pppoe
   virtual-template 1
!
!
vc-class atm PPPoE-128
   protocol pppoe
   vbr-nrt 128 32
   encapsulation aal5snap
!
vc-class atm PPPoE-384
   protocol pppoe
   ubr 384
   encapsulation aal5snap
!
!
interface ATM2/ima1.1 multipoint
  description ** subif 1**
  range PPPoE-1 pvc 8/35 8/36
   class-range PPPoE-384
  !
!
interface ATM2/ima1.2 multipoint
  description ** subif 2**
  range PPPoE-2 pvc 9/35 9/36
   class-range PPPoE-128
!--------------------------------------------------

When using PPPoE, is there a way i can define another virtual-template to be used under the 2nd atm 
subif?
Maybe i have to change the encapsulation from aal5snap to something else, but then will it work with 
PPPoE?

When using pppovlan (PPPoE over vlan) as encapsulation is there a way i can configure different vt 
per vlan?

PS: If i use PPPoA (and aal5mux), i can configure one -different- vt under each vc-class, so this 
scenario is working fine.
