I think I know exactly what this is. Assuming so, I vote for it too.
I just installed my 16 zone controller. 10 zones total - 9 dedicated to the yard and one dedicated to the pool.
this 10th zone essentially fills the pool everyday for a few minutes, using the sprinkler supply versus the house supply. Over the years you get to a good understanding of about how many minutes each day is needed as a function of season.
For conventional, non-flex scheduled controllers this is easy. You dedicate a 'program' just to zone 10, telling it to water every day at 4 PM for 5 minutes (for example).
Today, with my Rachio now installed, I set up my flex schedule - only water when it's determined to do so. But for zone 10, I simply want to water a few minutes every day. Seasonal adjustment would be nice
Instead I had to figure out how to adjust all of the setting to minimize run time. so that I can support zone 10.
