Info manage customers using vlan

Hi, I would like to manage our customers connected to APs 450 using SVLAN and CVLAN.
I would like to assign each SVLAN so a provider and then add behind it, n customers.
Customers routers would have same config using vlan835 for example.
in attachament details.
Is possible to do that?
I try but I have CVLAN in each router. I dont know how and if is possible to change each CVLAN to USER VLAN 835
thank you
