FusionPBX EXPERT Needed

Hi. I've got exts that comprise the same company but 3 different locations under the same domain. Each location has a DID and their own IVR. The issue is if I call Location A and use the company directory, I'll hear people from all locations. Can I put exts in a group and tie that group to an IVR or DID so they're the only ones that will show up in the directory? Looking to have this done
