Permission Ex Help

Hello, I need some help in my rank system for my server.

We just did a major update to the server and I would like to know how to make it so my ranks can inherit but not inherit all items. So for example
Rank Member can inherit everything from Rank Guest except:
- Essentials.Kits.Guest2
- Essentials.Kits.Guest3
So they will only receive - Essentials.Kits.Guest1 and then all the commands and stuff etc.

Guest:
options:
prefix: '&f[&6Guest&f]&6 '
permissions:
- Essentials.challenge
- Essentials.craft
- Essentials.Kits.Guest1
- Essentials.Kits.Guest2
- Essentials.Kits.Guest3

Member:
inheritance:
- Guest
options:
prefix: '&f[&6Member&f]&6 '
permissions:
- Essentials.clearinventory
- Essentials.Kits.Member1
- Essentials.Kits.Member2
- Essentials.Kits.Member3
