HotSpot User limitation

My first post, here goes…
Sorry if this has been covered before but I really dont know what to search for, ANYWAY

I setup a hotspot on my MikroTik with radius, all works, created some users using Mikrotik User Management and played with some limitations with regarding to speed limits, works, very nice. I also set the users to Unlimited Shared Users, it works, 2 devices sign in on one account at the same time.

Here comes the deal, I want the limit for that user to be the TOTAL across all devices. I set the user to 1Mb and I could reach 1Mb on both devices simultaneously, so that user can effectively smash 2mb and I dont want that.

I am going to love any help I can get, thank you inn advance!

PLEASE, does someone have any suggestions?
