Extending leg room

Is it possible to add new tracks to the front passenger seat in order to extend the leg room in the front? And who does this type of work?

Sorry- to a Nissan Quest

Doing so may compromise the effectiveness of the airbag and seatbelts. I’d be surprised in you could find a shop that would accept the liability of doing this for you. If you can it will probably be a shop that modifies vehicles for handicapped drivers.
