Glyph Member Properties

I see that the option “use this glyph’s metrics” in Composite Glyphs - Glyph Member Properties is omitted in Font Creator 14.
Is there a new way to link a composite glyph’s metrics to one of its glyph members?

You can use expressions for LSB and AW like:

=lsb(o)
=aw(o)

It works, thank you very much!
