Corner profiles in sketch mode (like Chamfers/fillets in modelling mode)

The problem that this feature will solve:

In certain situations, it’s easier to modify a corner in sketch mode than in modelling mode because of selection.

Brief description of the outcomes that you expect from this feature:

Select corner/edge point > drag out a corner profile (round/straight/custom shape) [Adobe Illustrator have this feature and it speeds up editing]

What can’t you achieve without this feature?

It speeds up production.
