How to express an octave played in slight off-beat?

Hi,

I want to write an octave pair of note (let's say a low C and a high C).

However, instead of the 2 notes being played together, the lower note is played first, then the higher note to create a slight off-beat feeling. But I think it's not as big of a time gap as a grace note, just a slight dissonance to the ear. The other difference with grace note is that the lower note will be held together with the higher note after being played.

Is there some Musecore notation that can help me achieve this in both display and playback?

Thanks so much!
