How do you have multiple triggers with multiple collectors?

[Rick_Wallen]

I have 4 issue collectors (a,b,c,d) and would like to have multiple buttons set different field values per collector.

ie 

button 1  (use collector a with field value collector = 'ex1')

button 2 (use collector b with field value collector ='ex2')

button 3 (use collector a with field value collector ='ex3')

..button n
