How to reuse a base shape in ligature?

Design
1

Hello,

One of the most useful features of Glyphs app is that it supports reuse of dotless or base glyphs.

I’m trying to figure out if there is a way to reuse a base glyph in ligatures as well?

For example, I have this base glyph:
base%20shape

I have placed anchors in this base glyph.

Is there a way to set this base glyph in such a way that it used by ligatures like the following:
child%20ligature

Thanks and regards.

In the base glyph, you need to add ligature anchors as in normal ligatures (top_1, top_2). Press Cmd+U to add them and then move them to the right position.
In the ligature glyph, add the base shape and the dot with Glyph > Add Component…
Then select the dot and in the info box, click the anchor and select the top_1 anchor.
