saving Overclocked mame settings

[Cave]

Some games run really choppy in mame just like they did in the arcade (Double Dragon, metal slug, etc..) overclocking them works really well, the only problem is when returning to the game i have to overclock them again, is there any way to keep these settings?, they don't seem to get saved in the cfgs.

I'm pretty sure you can't save these unfortunately
