There are a number of construction companies that use service orders/appointments to schedule workers on their projects. This is especially applicable if their workers are frequently moving from site to site in a given day. Being able to schedule this right from the project would be very helpful. It would also be nice to have a tab on projects that just has a list of all appointments that are associated with that project.
if possible, just generate an appointment right from the project, and have the service order be "X"
