Multiple Changes to Customers

Hi,

I need to change salesperson for multiple customers.  Is there a way to do it as a bulk change or something?  I've been going into Customer Maintenance and changing it one by one.  it's taking forever!  I went into Customer View in Explore under Accounts Receivable and the list comes up with all of my customers...is there a way to make changes in there or something like that, it would make it so much easier.
