OpenType Ligatures in multi-segment lines

Just want to confirm that OpenType Ligatures are not supported in Dorico for multi-segment lines?

The following example is only possible as a text expression. Here, each group of 3 wiggleTrill glyphs is replaced by a ligature. The last two glyphs are unaffected.

I could be wrong, but I don’t think that OpenType ligatures are used by Dorico for any music symbols.

It looks like this is the case. Only text elements support it.
