Running editor plugin on a project from command line

Ive created an editor plugin ( separate window editor plugin template ) that splits assets in to separate PAKs depeding on the asset path.
Rigth now its usable only from the Editor UI.

Im looking for a way to run this operation without launching the Editor, preferably CMD/Powershell.

The other solution would be creating a binary that is able to open a project, and initialize the AssetManager/Registry which seems like big programming overhead.
