"[Hello,
I've been using WKO+ and TrainingPeaks Premium for a few years now and there is really something I'd like to find a way to do with both (if possible ?). I happen to train mostly with 8 days "weeks", meaning one week is very often 2 times 3 consecutive days of training + one day off and so on. Which means if I'm doing 3 weeks like this before I take a rest week, I might start the first week on monday and finish it the next monday with a day off, so my first "WEEK" summary may be accurate as it cumulates from monday to sunday and since 8th day on a monday is off, then my week summary is good. But then my second week of training will start on a tuesday and from there my summary is wrong so I have to start and calculate things, quite doable but it means I need an extra calendar I have to deal with on my own other than Training Peaks. Same seems to apply to WKO+. So in the end I have to use WKO+ and TrainingPeaks and then an extra calendar in which I build my weeks the way I want and do the cumulative calculations in and so on...
I don't know if there are options in TrainingPeaks and/or in WKO+ to help me right now ? If not now is that something you could consider for the future ? I don't need much actually, if there was the standard WEEK summary available from monday to sunday and then in Dashboard the possibility to add a "CUSTOMIZED PERIOD SUMMARY", considering all the options you already have I don't think it's a complicated one to add and it would be so helpful for people like me who don't do monday to sunday weeks of training.
Another option would be to have with the calendar the option to set it in "customized periods / drag days in period" mode... Let's say you allow a period to be 1 day min, 10 days max, then you allow people to drag the days in the customized period so instead of showing one line = one week you show one line = one period and then number of columns depends on how use set "columns number" in the options.
So you can end up having let's say a 9 days period, then the next line could be a 3 days rest period for example, then next line could be a 8 days period and so on. Would make it much much easier to calculate exactly what we are doing in the specific period, etc.

So minimum would be a "customized period summary" same as "week summary" but with adjustable period.
BEST would be a calendar completely adjustable in standard weeks OR in customized periods.

Thanks in advance for your feedback on this.

Best regards,
