Multibrush Copy Translate Save Config/ Generate positions on grid

Hi all, New member here :slightly_smiling_face:
So I found this:

Has this been added to 5.1 yet?

Also any way with Copy translate with Multibrush, can a grid be used to generate positions of the brushes? Say I want to generate brushes using the Multibrush copy translate here:

Maybe a script or plugin that can do this?
