How to delete whole month's sessions in Fitness App in one shot? Possible?

In the fitness app on my iPhone, I have sessions for the last 5 months. I know how to delete items in Sessions one at a time. You select the workout and then swipe left and delete all workout data.

But I don't want to do one at a time. Is there a way to delete them at least by the whole month. It is very tedious to delete one by one.

I searched but all of them tells how to delete one by one.

Is it possible to delete at least a whole month or Apple has to come out with some new patch so that we can do it?
