Sketch, Constraints, Perpendicular by 3 points

[abramov]

Dear developers,

in Inventor we have 2 similar constraints,

1. Horizontal/Vertical by 2 points
2. Set angle dimension by 3 points

Could you please modify perpendicular constraint that she could set constraint for angle formed by 3 points (same way as angle dimension does)?

For example it could be set centered rectangular without construction lines.
