hello
i would like to link salesperson with particular contacts, so that each time while billing it doesnt ask me to choose, while billing it automatically chooses the linked salesperson

for example
i have 3 salesperson A,B & C
and 12 contacts 1,2,3,4,5,6,7,8,9,10,11,12

now in contacts i can add default salesperson
like A for contact 2,4,8,10
so whenever any invoice is created for say contact 2, then by default salesperson A is selected

thank you
