PCQ With Multiple Device From Several Users

Hi,

I’am new with Mikrotik.
Just had RB951G-2HnD yesterday.

I using this Mikrotik in my boarding house.
It have 6 user with several device per user (PC, Smartphone, Tablet) and all devices connected using WiFi
My bandwidth is 6mb download and 1mb upload.

I’am trying using Simple Queue to solve bandwidth problem, where is limit = 0. Then All devices get equal bandwidth when all device is active.
Then something bothering me, if there are currently 2 active user, where User A have 3 device and User B only have 1 device, then User A will have 3/4 of total bandwidth and user B can only get 1/4 bandwidth when all device is active.

My question is :
Is it possible to queue bandwidth per user ?
So no matter how many device the user can get, they will only get 1/6 of total bandwidth when all user is active.

Maybe the scheme will like this :
