Logic Pro 9 Midi Channel and Program change for MIDI Export?

OSX El Capitan Ver 10.11.6 Logic 9 Pro 9.1.8
I am preparing 5 regions for midi export and need to set the channel and program changes for each instrument (Melody,Guitar,Piano, Bass, Drums.) I know how to do this in the event window.

My question is.

Is it possible to change all the regions for one instrument at one time?(Intro,Verse,chorus,bridge,outro)

Or must I do it one region at a time. The regions are not merged but separated by a few measures per song section. (Intro,Verse,chorus,bridge,outro).

I hope my question is clear. English is my only language.
