Different number of visits on separate days?

This might sound confusing but please bear with me.

Example: Client requests visits for 2 days. On day one, they need 1 visit. On day two, they need 2 visits.

When booking a reservation, the website doesn't have an option to book a different number of visits on different days. It's either 1, 2 or 3 visits every day. So what's the easiest way to make the modification and have the price reflect the number of visits needed? I contact Rover everytime I have this issue but there has to be an easier way. Please help! Thanks yall.
