Time signature between staves

You have to use text to do this. It looks like a piano piece, if its a solo it doesn't matter if you use system or staff text, otherwise use staff text because you will need to do this on every instrument. First of all enter the correct time signature into the score. Right click each staff, choose Staff Properties, then remove the check next to show time signature. Next, enter enough of the song that you can put in a system break to make sure the system with the time signature does not get reformatted. All of this is because any of these changes will affect the location of text you enter and you will need to move the text again to where you want it. Since the text doesn't affect the rest of the score, do it last. So finally, enter the text, change it's size and place it where you want it. You can change the size of the text by using the toolbar that appears at the bottom of the screen when you enter or edit the text. All of the text has to be selected to change its size.

Disable the normal time sig and creams and add an image with that time suggest or a staff text.
