[Feature Request] Snap schematic to corner when pasting

[MegaMinerDL]

Feature Request

The Problem

Sometimes a corner snap would make it easier to paste schematics instead of just working out co-ordinates.

Feature Description

Snap paste to a specified corner instead of the center point.

Alternatives

You can use the numbers to manually work out fitting co-ordinates.
