could we have username column and email, as well as name, in sales listing

HI ewe use emerald 9..

we try to locate users email by having to search specific names 'name / user' column.. which are not unique.

It would be very helpful if a username column and associated email column, could be added to the subs list display columns.

is any of this possible?

Is emerald 10 any different from 9, in these sales display areas?

thanks
