cues in multimeasure rest

[David Bobroff]

What is the best way to do this:

It is a multimeasure rest with some cue notes stuck in at the end.  To
the performer they obviously belong to the end of the final measure of
the multimeasure rest.  The first, indeed the only, thing that comes to
mind is to put in a measure that fits the duration of the cues and make
the barline/time signature invisible before the cues so that it ends up
looking like the example above.  Any better ideas?
