Grace note attached to main note

Is it possible for the first note of a grace note group to share a note head with the first regular metrical note? (This might seem counterintuitive but essentially means, play the grace notes as fast as possible, then return to the first pitch as quickly as possible for the remainder of the duration of that note.)
I suspect it is not possible and I might need to use two voices, with the “grace note” voice being a smaller size?

Did you try fraphic tool to adjust the exact placement? Don’t remember exactly, but know, that there are things possible in Cuabse, which you can’t find in any other notation program.

I would be very surprised if you can’t accomplish this using the note spacing tool in Engrave Mode. Though I haven’t tried and am not near a computer.

Thanks for that. It’s a bit awkward, but it works.
