Wheelchair lift

Hi all, I'm looking at a mini bus with a wheelchair lift that opens and deploys the lift. I'm going to do a handicap accessible build and had a question for those that have done one. How would I go about doing an outside control for the lift? Seems like a no-brainer that you'd need to be able to control the lift from the outside to enter it if you are in a chair. Anyone ever done a remote control or maybe an external actuator? Thanks in advance!
