Putting a second time signature in the same bar

Hi,
I have a piece of music for Brass Band that I am in the process of transposing the Bass Trombone part to be played on a Tenor Trombone.

The original piece has a section which is written in 4/4 time, with (2/2) marked directly after the 4/4...

My question is, is there any way I can make this appear in the Musescore version? If so, could someone please enlighten me as to how to achieve this.

Thanks heaps.
