Connect gliss to custom line?

I am not successful in finding out, if it is possible to connect the “native” glissando playback feature to a custom (glissando) line. Can anybody direct me to the proper place in the documentation, please? Thank you!

No, it’s not possible to do this.

Thank you, @dspreadbury !

May I suggest to add a “custom text” field? Much like with the custom lines feature? Would be great!
