Edit pool length for an open swim activity after activity completed.

I’ve just completed a swim at a pool I do not usually swim at.

I didn’t realise the pool was longer that my usual pool until after I had completed the swim!

It was 33 1/3 yards not the usual 25 yards so I’m obviously a few yards short on my activity!

Is it possible to change the pool length on a completed activity?

If not can that be added as a feature for the future upgrades please?
