Relay Map?

[ranger2kxlt]

I run and own a Car website, for the Ford Thunderbirds. And my members have started what they call a HardTop Relay, where each member from the seller to the buyer, will relay the Hardtop. Saves on shipping, plus my members just love to drive their birds around. Anyways, I have looked at this hack https://vborg.vbsupport.ru/showthread.php?t=51731 and installed it.

BUT, can someone create me a hack where the user can input from where to where he can drive, and it will create a roadmap? That way, if another member can pick the item up in the last membes stopping point, they can type in where they will take it?

EX:
Getting an item from Orlando, FL to Albuquerque, NM

Member A can take the item from orlando, FL to Atlanta, GA The map will show a line with the members name.
Member B can take the item from Atlanta, GA to Dallas, TX The map will add another line (perfeablly different color) with this users name to the same map.
Member C can take the iem from Phoniex, AZ to Albuquerque, NM and the map will add another line, different color, with this username.

This way we can see what areas need to be filled in (in my EX from Dallas Phoniex needs filled)? And hopefully if a member lives in that area, they can close the gap??

Hopefully this makes sense. Can anything like this be done? I would appericate this. Might be willing to offer cash.

Thanks!
