bandwidth assignment / limit per access code

I have raised ticket 22010289
Now, I am requesting the feature. “Bandwidth assignment on access code basis / bandwidth limit per access code”

Actually, I want to give a single access code for each department, and each code will have a different speed.
Given example for 2 departments,

Building Service dept.
access code: 112233
concurrent session: 10
speed: 10/5 (10Mb upload / 5 Mb download)

Business Development dept.
access code: 112244
concurrent session: 10
speed: 20/10 (20Mb upload / 10 Mb download)
