Scott,
If I understand your question, you want to do scheduled conferencing on the RMX. This is totally doable, both ad-hoc and ahead of time. In the RMX gui, there is a section under frequently used called "Reservations," if you go to that page it will bring up a calendar page and you can schedule conferences by selecting a time on the calendar, adding participants (either manually by alias/IP, or by dragging them from your address book) and choosing a conference profile.
At the appointed time, the RMX will dial out to all of those participants and start the conference automatically. You can also create one-off conferences by right clicking in the active conferences window and selecting new conference. Then you can choose a conference profile and add participants, and it will begin immediately.
