> Brief title for your desired feature:
Add pre-defined shapes to the 'Solid Region' tool.
> How would you like the feature to work?
Be able to select shapes, similar to the 'Pad' tool. Be able to easily create circle/square/etc cut-outs and NPTH
> Why is this feature important to you?
Making a polygon each time for a standard shape is time consuming and awkward. The ability to make circular copper area cut-outs would add to the possible aesthetics of a project, versus square or octogon type shapes.
Brand new interactions and interfaces. 
Easy to use and quick to get started.
