Sure would be helpful for retroactively adding tags.

Still would love to have this, I keep wanting to update my exist with historical data I have. Any ideas for a workaround? I could probably get stuff into e.g., a CSV or other format if needed.

You could use the API as a workaround if you’re coding-inclined.

I’ve considered it, but unfortunately there’s this little “as time permits” constraint that keeps stopping me from doing fun little coding projects. ;)

it is very sad, because this function is very important. I track events like school holidays. it is hard to remember every day to write those in. so I could check later, if I didn’t missed any, and add, if I did

What if in the tag grid view you could just click a space to add or remove the tag for that day, so you could just go down the line?

I like Stephen’s suggestion of using the tag grid view to bulk-add tags retroactively.

My use-case for this request: I’m about to hit a 300-day streak of journaling, and I would like to be able to retroactively add the “journal” custom tag.

Would be very useful for many reasons. Sometimes you can not (or want not) “work” on your exist stats for some days. Entering data day by day is possible but bothersome. Also, if you create a new tag, you might want to add it also for the past. Most of the times, the tag existed already in the past, even if you thought about it only today.
