Move static mesh in editor by a set distance?


I’m working with hexagonal and pentagonal tiles and its taking forever to position these in the editor.

Is there anything like some kind of radial snap-grid, that snaps the actor to a position X units (whatever the radius of my tiles in this case) away from the original pivot, keeping them mobile in the x and y planes but with no movement in z?

Failing that,
I know its possible to manually enter a global position for an actor in the editor (under Details Panel>>Transform>>Location), but is there any way of entering a set distance for an actor to move from its current position, so I can move actors by set increments WITHOUT having to turn on the snap grid?
