Irregular multi-measure rests

In my current pursuit, I seem to have run into a rather halting quandary that has left me in a state of quaint perplexitude.

Take you: I have now at my hand a second movement in a four movement cycle; the full score of the cycle is complete, and I sit now at the task of compiling separate scores for the solitary instruments involved.

Several instruments sit tacet during the whole of the first movement, and as such, I think it thoroughly appropriate to include those measures of mute tacetry, not as a single leaf of music, void of intrigue, but rather as an extension of the second movement.

Upon the creation of Movement II's lead page for said instrument, I insert sixty-eight measures to represent all bars of the previous movement; all measures are, in turn, held bound as a multi-measure rest. All well and good, as I then proceed to further distinguish these bars from the Second Movement proper with adequate spacing and labeling hence (a line break and title, respectively).

It is here that I meet my botheration. I select said multi-measure rest (as a measure, mind you, not a rest) and select that it be stayed as an irregular measure, that it may not be held toward the counting of the proceeding measures that account for the true second movement. Verily, it works; the selected measure rents apart from the multi-measure rest and stands solitary and counts irregularly; but it is now no longer held as part of the multiple rest collective.

I have duly made certain that none of the measures are selected to "break multi measure rest" as that would be a most embarrassing outcome. I have also attempted to use negative values in the "add to measure number" field, but to no avail.

Is it thus possible to create a multi-measure rest, thence unbroken, that counts fully as irregular?

With sincerest gratitude -
