Why can't Sitters charge travel costs for Meet and Greets that are far away?

I set my Meet and Greet travel radius to 50 miles. 50 miles round trip to do a meet and greet can be costly. Many sitters do not offer boarding especially here in Upstate New York because they rent a house or apartment that does not allow pets, therefore the client can't come to their home because they live in an apartment that does not allow pets. I had many owners ask me to come to meet the dogs up to three times and I had to travel long distances for the Meet and Greets. I wish Rover had an option where sitters could charge a rate for the Meet and Greets if they chose to, or offer it for free within a certain mile radius that sitters specify. Most owners want to have the reassurance that they can trust their sitters, and they ask sitters to come more than once to spend time with their pets, many people want you to come at least two times or more to get to know their pets, build trust and spend time with them. I think there should be some kind of option where people can request additional Meet & Greets, and there should be an option where Sitters or can set their own travel costs. I don’t think it’s a good idea to limit the travel distance, 50 miles is not a very far distance to travel. I think a sitter should be able to travel long distances to help a family with their dogs if the family can't find another sitter, traveling gives sitters a chance to build their networks and does not limit them to a small radius. Thank so much for reading my suggestion.
