Suggestion for disabling Interactor

Just wondering if there is an official way to disable interactor within the original scripts.  For example, I don't want the poke to work unless the hand is pointing (grip button pushed, index not touching, and thumb doesn't really matter).  I made a script that disables the interactor gameobject if the grip is not pushed but it seems like this is something that ought to already be built in.  I'd prefer to use built-in if available because it seems that whenever I make my custom scripts then they always get broken with future meta updates.
