I like the app/site but since data is dependent on user enrichment of data, a bulk update/edit is severely missing. Example: Runalyze will not automatically interpret data for routes (such as Strava), so updating routes will lead you to go though 5 years of data line by line. This is not really feasible leading to a lack of use of this function.
The same for tags, etc., and several other elements.
Is this function on the roadmap?
