Customize Role by level

[hieptd]

Hi, can you update a version that supports level-based role customization?

Hey! Sadly, I'm too busy working on other projects at the moment.
I'll keep this issue open and maybe do it eventually, alongside an overhaul of the system itself (including an update to DJS 14.)

But feel free to fork and edit the project as you like!
