I've run up against this several times, but I've never found a suitable way to write it.
Let's say I have a C triad broken up and played in eighth notes (quavers), but I would like to have each note held till the end of the measure. In Sibelius, I could split it into separate "voices", making the first note a whole note in one voice, and the second and third note another voice. Like this:

But, that doesn't seem right to me.
How would you handle this?
