We have some add-ons that require time (i.e. gel polish removal) but need to be booked in conjunction with an original service and with the original therapist. So, for example, if a client books a manicure and a gel polish removal, separately, what usually happens is the manicure would get booked in a tight spot on one nail tech, and the gel polish removal will get book AFTER the original manicure on a second nail tech. We won't have wiggle room to rearrange this. We created separate services to include the removal time, but this is inefficient. Can you please make add-ons that DO add time and function similarly to the zero minute? It would be great if our nail appointments would have these options pop up for online booking and internal booking as well, to help remind clients to book their gel polish removals, for example, and then only show openings where there's room for both services.
