Organizing / grouping runs for lifemap?

Would anyone have use for organizing or grouping runs to show up in lifemap? ex. using a hashtag in Strava as description that could be gathered, like if you wanted to see a visual of all your half marathons #halfmarathon, or certain races like #5K #10K etc.

I’ve been marking rail trails #RailTrails2021

Thoughts? (Or is this already a feature I’m not aware of?)
