Add more infos in POS

When I type mobile no of customer it show: 1. All Customer Groups, All Territories, General and Mobile Number but I would like to add more info in POS like Discount for being easy to know which customer will be discount how many percent?

Add More Info in POS

Could you advise to do it?

Thank you.

Maybe just include the number in the name, at the end?
