Piano score with two key signature

[Mark I]

Hi. My problema is, how to get in a piano score two different key signature. I mean, in G clef an A major key, and in the F Clef, Bb major key. Bitonal write. Thanx!

1) Key Signature Tool.
Set the key signature to 3 sharps (= A major).
Now both staves display A major.

2) Staff Tool.
Double-click the lower staff.
The dialog box Staff Attributes appears.

3) In the pane Independent Elements, select "Key Signature".

4) Go back to the Key Signature Tool, and change the lower staff's key signature to 2 flats (= B♭ major).
