Hi Florider,
Requirement: Need to edit the control point of the shapes.
We can create polygon shapes using polyline tool as well as geometry. Currently, we don’t have support to edit the shapes using control point. We have already logged the feature request for the same requirement. We will implement this feature in any of our upcoming releases. We will update you once the feature is implemented.
Now you can track the status of this request through the below feedback link:

Ranjitha A.
