Grace note at last measure of a flow

Hello all, I’m having trouble inputting grace notes as in this picture. Because it’s the end of a flow, there’s no following measure to place the grace notes in and select the “grace notes before barline” property obviously. Is there some kind of a workaround for this?

I would create a second voice, enter the notes on the last two sixteenths of the bar, flip the stems to upstem, delete the rests created in the bar (edit > remove rests), select the sixteenths and scale them to grace notes in the properties panel in the bottom area.

That’s quite clever and works just fine. Thanks klafkid!
