Shop problem

I’m the owner of a DarkRP 2.4.3 Server and i have a problem with my shop. I added weapons, shipments, entities and they work. The problem is that every job can see the items in the shop.
Is it possible to make them appear only for jobs like Gundealer ? I know that for 2.5, there is an option in the config but for DarkRP 2.4.3, i didn’t find anything.

Thank you and sorry for my english, it can be bad because i’m french.
