CID group on inbound routes?

Hi, we have an IVR menu and we’d like to change it for some customer. We base the ivr on CID, but it seems there’s not the ability to create a customer list/db, but single route for single CID

is it true?

Have you found any solution for it? I have same need!! I need to rout all incomming calls from a specific group to related extension.
I’d appreciate it if you can help.
