Independent Sidebearing in Multiple Masters

Hi

I’m sorry if the topic has already been touched but I found only old records for Glyphs 1.
Is in the new version of Glyphs 2 possible to create an independent dynamic sidebearing and independent group kerning for each master?

You can have metrics keys per layer by using a double equal sign.
Kerning groups are always for the hole glyph.

thank you
