Surname Order

I have always used the Myob Desktop version, however recently we have been swaying to move to Xero or stay with Myob.  I have been comparing Xero with the Myob Browser version (comparing apples with apples compared with the desktop version).  What I have noticed, which is a huge red flag for our business, is the Myob Browser and Xero have their customers (and employees) listed in first name order.  We have to have our customers in surname order for ease of use, otherwise we could end up with 100's of John's etc listed in order! Please tell me this can be changed in the Myob Browser version, so we can move over from the Desktop version. Surely this is an issue for other businesses.
