What I did: Exported notes with graphics from Craft as textbundle into a file folder.
What happened: Import->Textbundle into Agenda. In Finder dialog, I can select only one file from the folder.
What I expected: Abililty to select all files from folder.
Things that might be helpful to know (Agenda version, OS and model, etc):
Agenda version 14.1.1 (231) - Mac App Store
MacBook Air (M1, 2020)
macOS Monterey version 12.4 (21F79)
