Tags have been around for years and I should be able to add multiple tags to a booking, and then be able to search, sort, filter and generate reports by tag. This eliminates having to get ISN to make code changes and/or to have an admin try to standardize across franchises or even many companies, which isn't feasible. Tags make software valuable to users quickly, and avoids inflexibility of standard software, or having to go through some sort of admin role.
