Add column for present status in participant PDF export

Is your feature request related to a problem? Please describe.
Often it is required by law, that a list of members is presented to court for certain legal steps (ballots etc.), from which attendance and the total number of invited members is clearly visible. Currently you can filter and sort the attendee-list exported to PDF, but it is not possible to select columns or to make actual presence visible.

Describe the solution you'd like
Add a possibility to show a column for member attendance in the exported PDF. Maybe use marked or empty tick-boxes from UTF to clearly symbolize the state of each member in the column.

Describe alternatives you've considered

• Currently we prepare a list from the CSV, which has all information in it. But it does not fit the uniform styling of the other documents.
• You can filter for attendance, this making two lists. One of present and one of missing members, but this is cumbersome to interpret.

Additional context
Heartfelt thanks for the good work, folks! Your tool made lock-down manageable for our small non-profit! Without, we would have had a hard time fulfilling all legal requirements for member-assemblies and stuff via internet.

Cheers,

Jörn

Start by locating the participant PDF export entry point and the attendance data used by the attendee list. Confirm how PDF columns are selected and how present or absent status is represented in the application. Done means the exported participant PDF can show a clearly distinguishable attendance column while preserving its existing styling.
