Possible to add a stamina selling stall at job centre?

Seeing a lot of people both selling and buying stam in global chat and wondering if it could be cleaned up by settings up some open stalls at the job centre where people who want to sell stam can make themselves available and people have a central location to go buy without needing to spam global.

Possibly set multiple stalls with set prices on signs (10GB, 11GB, 12GB or ask for price) to make things a bit more streamlined.

Ideal place for it in the open space beside the portal beacons.

Anyone think this could be good? Would help cut down on global spam anyway :)
