Once loaded, the :padstackedit() command can be used to bring up a dialogue window which allows you to alter the plate through plating status of the through hole padstack/via hole or slot. The user can also edit the apertures on the various layers, i.e. top copper, top soldermask, inner copper, bottom copper, bottom soldermask. For a single sided board, you could in theory remove the top copper, inner copper and solder mask apertures. There is a visual indication in pcb-rnd of a padstack's plate through status, which can be seen to change when toggling the status. There is also an explicit fab layer visible in the layout editor, which can be viewed and also have text annotations added if needed. More advanced techniques can use the built in search tools within pcb-rnd which allow objects with particular properties to be selected, and then have properties set. Once the padstack properties have been modified, the layout can be exported with the CAM export menu item. This allows CAM exports such as gerber to be scripted for particular end applications, but there are plenty of supplied standard formats, including seeed, oshpark, universal, eagle format etc... which target the particular naming convention for the given manufacturer. Some manufacturers will merge the unplated and plated hole files anyway, but if the gerber and excellon files properly show which holes are unplated vs those which are plated, and the top layer has no copper features, that might make things more explicit for the manufacturer's pre-manufacture checks of a single sided board.
