Glissandi on two notes from grace notes to main notes - possible yet?

Sliding on two strings or more: is it possible to notate this? I do not mean “scoop” notation: I mean glissandi from two simultaneous notes (a diad) from one diad to the next. So far, when I select two notes and add glissandi, it only attaches to one of the two notes, usually from the lower note of the first diad to the higher note of the second diad. This is completely useless to me and anyone writing for guitar. See images: the smaller one with 1/8th notes is what I am trying to achieve. The one with ¼ notes is a screen capture from Dorico.

Have you tried inputting each glissando individually - so select the top grace note and the top normal note, then input a glissando. Repeat for the lower notes. ?

Thanks for your tip. John Barron got back to me with that exact solution. And then there are adjustments that need to be made in preferences to narrow the gap, although John admitted that making the gliss close to both notes may have bad consequences for normal glissandi…
