Hi Akshath,
It's very common for Dogtag users to create customized profiles
themselves.  So creating two profiles with each tailored to what's needed
is what you need.
The RHCS documentation should cover it. e.g.:
https://access.redhat.com/documentation/en-us/red_hat_certificate_system/9/html-single/administration_guide/index#Modifying_Certificate_Profiles_through_the_Command_Line

Hope this helps,
Christina
