sms search by user/uid

In SMS im able to search by PC, etc.. but would be nice if possible to perfrom a search by UID. When busy and problem seems to be a quick fix. I usually remote in via sms and correct the issue. I have to ask the user what their computer asset tag is (how we name our pc's) and half of the users and lost, even though the sticker is a shinny metal sticker on the computer. So trying to make it a less painless way of searching
