Any way to add profile name ( MS: 1.3.6.1.4.1.311.20.2 ) to certificate?

[filimonic]

Want to make all certificates provided by dogtag human-identifiable.
I think good choice is to add certificate extension 1.3.6.1.4.1.311.20.2 where a profile ('template' in MS terms) can be stored.
Could not find a way to implement it.
