is controlling 3 servos with 3 potentiometers and 2 Xbee modules possible?

Hi
As stated in the subject, I am trying to control 3 servos with 3 potentimeters via a pair of Xbee series 1.
As far as I know, all xbee modules, however, only contain 2 PWM pins. is there any other way to do that? Or another pair of xbee modules is required?

N.B Currently I am using a arduino UNO at the receiver side only,

Your reply and help are much appreciated!
