Fields that appear in Master Calendar view

I have Date fields with Show in Calendar = Yes, and I am trying to figure out which fields or more to the point, how to control which fields show up since the calendar item has limited space. Fields that don't tell me exactly what helps with the reminder of showing on the calendar is needed for. For example if I have two date fields for a record, one for Contact Client Date, and the other for Final Payment Date. The challenge is the Calendar item uses "Table Name" and First Field in the Record, Second Field in the record and so on. It has a limited number of characters so if the field first is long you only get the table and first field (or part of it).

Any idea if these can be selected or somehow controlled?
