Hello,
I have been using Xert for nearly a year now, and I still have a few questions…
Regarding Forecast AI: how can I “pin” an activity created using manual XSS values? I have never seen a “pin” option for activities—such as simulated races or workouts—that I would like to keep in my schedule.
Also, regarding XATA: I occasionally simulate my training weeks, but then I have to delete each activity one by one. Is there an easier way to delete multiple activities at once? It would certainly save time to be able to remove several activities in a single action.
Thank you for your help.
I think this article covers all the bases for XFAI.

There isn’t a quick way to remove a bunch of planned activities from the Planner.
However, you can enable Show Planned Activities under Activities Table, tick the ones to remove, and select Delete.

Fantastic! I’ve just pinned my first activity after a year of using Xert—thanks a million, Ridge!!!
And This is exactly what I needed to delete multiple activities—the day is off to a great start! Thanks a lot for the tip.
