Sure, and in no way was I discounting your specific post and request. In the one reply I made above, I merely addressed a solitary (and slightly Off Topic) concern from the reply that I knew had at least some relevance to an existing feature request.
Honestly, I like your request and it’s one that has been mentioned in various places for several years. TR has mentioned Training Camps and Training Blocks on more than one occasion, with targets just like you mention (VO2 specifically and likely others).
That said, this is likely better set as a “Feature Request” which would push it into the “TrainerRoad Software” category rather than “Training” where it currently resides. I left it as is to see what others posted before doing anything. We could get @IvyAudrain to comment and let us know if she has a preference WRT what makes the most sense in getting this idea into TR’s hands.
