Our meetings have two fields, at and participants, which don't show up anywhere on the meeting tiddlers. Create a new template tiddler, MeetingInformationTemplate, and add a table something like the following.

| !Time|20200531013141000|
| !Participants|JaneDoe|

Obviously, your version should include the correct information for whichever tiddler the template is being transcluded into. Don't miss the space before the ! in Time and Participants in the wikitext, which causes the headings to be right-aligned rather than centered.

Transclude this template at the top of all your meeting tiddlers.
