extra staff for keyswitches

Hello,
I use Eastwest gold orchestra , and there is no Notion's presets for it yet so I wanted to create another staff for keyswitches, so for example:
staff number 1: Violins MIDI channel 1
staff number 2: Violins MIDI channel 1 (for keyswitches)
But every time. when I create new staff It has (perhaps) different Midi channel . Is any option to change midi channel of each staff as I want?
Cheers,
