Running Y/N in weekly availability

Would be great and useful to have the possibility to choose days you want to go for a run in the weekly availability tab, by using a Y/N box or swiping something.

Sometimes when you dont have much time it is easy to go for a 45min run, but then it chooses a ride. And when I have 3 hours available it gives me a 60 min run.

Would be handy to be able to select the days you want to go for a run in advance.
