[Feature Request - Widgets]: Custom snap sizes. Batch relative transforms

[Feature Request]: Add additional or custom snap sizes for UMG widgets.

Custom snap sizes:
When using optimal texture sizes (16x16, 32x32, 64x64 etc…) as widgets on a canvas (think of buttons on a keyboard) you are (from a design perspective) likely to use similar paddings between them, not uneven paddings of 5px or 15px.

Also, improve batch processing of transforms on widgets positioned on a canvas.
I want to be able to quickly transform things relative to either a pivot point or relative to one another. Using the keyboard image as example: I want to double the size of a set of widgets , while doubling the padding between them, while moving them away from a pivot point. There is no such thing currently. Scaling / Scalebox does not do this properly and can not be applied permanently.
