I have a similar request, but implementing might be a lot of work, so I'm just adding my 2 cents!
I have multiple customers that I work for during the week, so for each activity I put in a tag for which customer it is. When I go to export I can just do a different filter on tag each time to get individual customer reports for the week, or alternatively, I can export everything and use Excel to produce the 3 different reports via filtering/save as. It would be great if I could just save the 3 reports as different templates and choose one in the export frame.
I'm just trying to save myself some work 🤣, so this isn't anything big, but would be a huge convenience! So, I'm just adding a +1 to the request.
Love the products (iOS and MacOS), keep up the great work Timo!
