Adding a time signature to a multi-measure rest

Is it possible to add a time signature to a mutil-measure rest measure? I have a piece where the time signature changes over a long period of rests. I set multi-measure rest breaks at all the measures I wanted, and then set the style to include multi-measure rests. Where there was a time signature change, I lost the time signature and ended up with a single rest mesure and cannot really delete it or add the time signature back in. I would simply like to place the time signature inside a multi-measure rest.
