Multiple staffs with different key signatures for warm-up scale practice

I want to put my warm-up scale practices on one sheet of music. I need to write separate lines of treble staff for brass and each will be in a different key so I can practice various key scales.

I can't find a way to write each line of scales in different keys. It would seem the software only allows one to write in one key and time for the entire sheet but I might be wrong and hope someone knows how to work around this.

Aside from this difficulty I love the program. There is a learning curve to be sure but the more I learn about it the more I love it. It has also increased my understanding of reading and interpreting sheet music as I try to write music that I have heard and want to transcribe.
