Suppressing breaks in multimeasure rests at instrument changes

Is it possible to avoid a break in a multimeasure rest at an instrument change? It is very common and desirable to specify a change of instrument during an extended section where the player is resting. MS breaks multimeasure rests at this point so that there is always a barline after the change.

I have cludged an example (1) to show what I would like to see if I attach an instrument change to the rest in bar 3. Example 2 shows what I actually get when I do that. Multimeasure rest break at instrument change.mscz

Note that example 1 doesn't represent a work around as what looks like an instrument change is actually just a plain stave text attached to the last note in bar 2 with its offset adjusted to bring it over the multibar rest. The instrument is Bb clarinet throughout example 1.
