Does it possible at ACS to authenticate devices based on Group ?

Group A devices uses username1 and password 1

Group B devices uses username 2 & password 2

Group C devices uses username 3 & password 3

Note : Devices uses HTTPS + Basic authentication.

If it is possible ,where can do the changes ? I am using GenieACS 1.2.6 code

How many username and password we can have it in our DB? or what is the maximum limit we can have if each individual devices uses unique username and password ?
