[Observium] adding a few 100 devices - group associations

Hi all,

I'm looking at adding a few 100 devices to Observium shortly. I don't see any issue adding them, as I can use a filename structured as requested.

This is for a few clients of ours, I'd like to trial observium as a customer facing solution. Add a user to view their devices only.

Is there a way to script giving a user access to so many devices ? Perhaps to group them. Has anyone done this and found issues with a large number of devices ?

Regards, Ross.
