Possible to have switch between 31khz and 15khz like in groovymame?

Hi, I have AtomiswaveSD candy cabinet which can support 31khz and 15khz.
I'm wondering if raspberry jamma + arpicade can support 31khz mode and can switch to 15khz mode instantly for 15khz games?

It would be possible in the same way it uses 480i for menus and 240p for games by default, however there isn't a pre-programmed mode to do so. As monitors that can do both low and high res aren't that common there hasn't been a request for this before that I can remember. I could add this functionality in the future if there's interest.
