Check unbuilt lighting from command line

Hello
For some time now I am using DumpUnbuiltLightIteractions to check if there is missing baked lighting for my levels. This command is very helpful, but I know how to use it only from within editor.

I would like to use it without opening editor, preferably by commandlet.

For example there is a commandlet to build lighting -run=resavepackages -buildlighting which I like to use, but since project grows bigger is hard to keep track of everything.

Is there a way how to check number of unbuilt light iterations from windows command line, without me having to launch the editor? This would be great improvement as it would allow to me automate light building process.

Thank you,
Jakub
