Trying to duplicate a Master with all glyphs

Is there a way to do this in Glyphs 3? I just want two Identical versions of the same master so I can then create an outlined version of the same weight. I also just installed all of Mekkablue’s scripts not sure if there’s a script in that pack for this. Attached a file below for reference of what I mean by “outlined version”

Also not sure if this is the best method for creating an outlined version of the typeface.

In File > Font Info > Masters, drag the master in the sidebar, and while you drag, press the Option key. A plus symbol will appear. Once you release, the master will be duplicated.

Or you simply set up a another instance in Font Info > Exports with a filter custom parameter.
