Set MetricsKey to none?

Scripting

Is there a way to ‘expand’ the metrics of a glyph made up of components. Scenario:

I’m making tabular glyphs and I generated new glyphs with:
one=one.tf
two=two.tf
(and so on)

now I run “Disable alignment for selected glyphs” over the new glyphs. But the metrics are still linked, how can I expand them so they are just the metric value without the link?

Running something like

Doesn't work either. The metricsUI just become: "==None (59)"

and

Doesn't make any change

Ok I answered my own problem again.I had to do thisGlyph instead of thisLayer
