The options are virtually endless here.
You can create VOLUME and PAN envelopes for the Track AND the Track Send.
You can right-click the Send Pan and set it to "Follow Track Pan".
(In X2 I don't see or hear this actually working. Does it work?)
You can place the reverb in the Track where the Track controls will effect the reverb also.
You can place the reverb in a Bus with or without a PAN envelope and set the Track output to that Bus.
You can place the reverb in a Bus with or without a PAN envelope and set the Track output to the Master and create a Track Send to that Bus.
Experiment with the possibilities to get the sound you want.
