Tooltips are used to give short descriptions of activites which contain activitiy content.
For example, a Trailer Sanitation record might have a tooltip of "Trailer: [[trailer_number]]" which would be displayed as "Trailer: 12345" after replacing the placeholder with the trailer number.
Placeholders pull their information from the record answers with a few exceptions.
Exceptions
load_number Fetched from the assocaited load instead of the record answers.
trailer_number Fetched from the assocaited load instead of the record answers.
location_id Fetched from the assocaited location instead of the record answers.
