Support for creating custom domains?

[winniepe]

Hi,
I wasn't able to find a way to add new domains (other than the pre-populated entries: enterprise-attack, mobile-attack, and ics-attack)?
It would be very useful to support defining custom domains for cases where one wants to threat model a specific scenario which is quite different from the supported ones and to avoid polluting the existing domain(s) with unrelated data.

Looks like the domains are currently hardcoded in app/config/config.js and app/config/allowed-values.json? Would adding the relevant entries to those files be enough to support additional domains?
