multiple pptp clients base PCC

My ISP provides PPTP dialer which I connect first in order to use internet. Can I connect multiple pptp dialers on same mikrotik to do load balancing using PCC.
I have worked with PCC but only with pppoe dialer (either via direct mikrotik ethernet or using vlan interfaces or static gateways , but with PPTP dialers I don’t see any option to select interface. like pptp1 dialer should go via ether1 & pptp2 dialer should go via ether2 but the ISP PPTP/VPN server IP is same
is it possible using any method ?
