Keep both min and max in one "Keep min/max" action

Greetings,

I’ve never noticed this transformation : “Keep min/max”
It helps to get a skyline analysis
Could you make it evolve to have the possibility to keep both in the same transformation ?
one option group for the smallest and one for the biggest.
I guess you’ll add that to the features request.

Regards

Yes, moved to #feature-requests.
