[Feature request] Select multiple workouts and delete them all

I have my Garmin account linked with Trainer Road to synchronise cycling workouts. After a few months, I have 5 pages of old workouts:

I'd like to do a small housekeeping but the only option now is to select three dots, then "delete" and then accept the popup warning. And repeat this hundreds times

Request - please provide "Select all" option for mass delete.

Thank you,
Jarek
