Lock certain acpect ratio while grabbing screen?

Description

Hi,
great tool, the Greenshot screenshot
Wondering if it's possible to add the following function:
1.) enter aspect ration e.g. 16:9
2.) drag a window over screen with the ability to resize the box diagonally (without change of aspect ratio!)
3.) then lock box size (px) and drag box to the final location
4.) then make screenshot
