About some Rhino functions called in grasshopper

Hey guys, I’m still learning how to use Grasshopper in Rhino.Its amazing,I see a lot of instructions&buttons in Rhino’s interface which is abundant and useful.And quantities of them were displayed as batteries in GH.
But still there are some instructions didnt have corresponding batteries.I wonder if i can call library in RHINO directly from GH.For example,“bridge” (a way to join 2subd)is an instruction in the subd class in rhino7,so is that possible to call the function"bridge" in gh?maybe through the ghpython or c# battery i guess?
hope for your guidance with my greatest appreciation.
