Hi JAFrank,
If your driver supports calling media as opposed to trays, you may be able to use this functionality through the "Advanced" settings of the Page Setup. Although the tray will still default to "Auto Select", it should take the media setting from the driver.
If that doesn't work, however, then the only other way would be to use the "Embed PostScript" option from the File menu, where you can enter postscript commands. You'd have to figure out what command to enter, and it could be different from printer to printer(and might not always be an option...). I unfortunately do not have an example to give you for this. (my knowledge of pure postscript is rather limited...)
