Sub-categories and Archiving

What I did: Created a Sub-category and multiple projects within it (all part of the same project, but broken out into different areas for instance meeting notes, references, comps, etc.)

What happened: Unable to archive the overall Sub-category, only the individual project within it one-by-one and then they are not grouped within the sub-category together

What I expected: Any way to archive a sub-category and keep it’s enclosed projects intact?

Things that might be helpful to know (Agenda version, OS and model, etc): Agenda for Mac v13.0

Archiving is currently something that can only apply to projects, not to categories I’m afraid.
