No. I suggest that you use
cycle.travel to do that. Export each route as a GPX file on the computer. As
@cyberknight says above - connect the computer to the 200 using a USB lead. Copy your route GPX file into the 'Garmin/New Files' folder on the 200. When you next boot up the 200 it looks for route files in that folder and processes them ready for use.
Navigation on the 200 is by following a primitive route line. There is no map under the line - you are basically just following a squiggle on the screen! If you plot your routes on cycle.travel they will follow every twist and turn in the road so the squiggle exactly follows the direction of the road. It sounds like it wouldn't work, but once you get used to it it is a very reliable system.
