Does anybody know if it's possible for one to attempt to switch over to the Guard for a PV slot if you get passed over for Major in the Reserves?

For example...You get passed over once in the Reserves but prior to getting passed over twice you apply to a guard unit which has an open Major billet. (I have heard that PV spots in the Guard are more of a local decision as opposed to meeting a promotion board in the Reserves)

Thanks for the help
