Calendar booking to display guests + pets w/ name

Currently the calendar displays the name and number of guest total in parens.  i.e. "John Jones (8)".  It would be helpful if this could be broken out with Adults/Children/Pets, maybe as an option or preference.  i.e. "John Jones (4/4/1)".  There probably a lot of options you could put on each booking and make it over crowded, but having a few self configurable options would be nice.
