A lot will depend on your data, but assuming that every driver has an address and every dealer has an address and you just want to toggle between the two - just create a parameter and use that as a toggle (Driver / Dealer) between the 2 addresses.
I am not exactly sure how to accomplish this. On other maps where there is a single address I added the lat and long (generated) to the columns and rows, used the number of records as the size and then placed the zip code, city and country in the text. How would creating a parameter allow me to switch out the text from one zip to a different zip?
Do you have some dummy data to post ?
Even if it's a few dummy records for driver and a few records for dealer
