Introduce a new bug type record in Aha! develop

When using Aha! Develop to track bugs I want to see specific fields that are only relevant for a Bug record. EX. Severity, date raised, reproduction steps etc.

So that I can report on this specific subset of record types and their progress without seeing other types of records.

I do not want to create a custom feature or requirements record as some of the fields are only relevant to bugs.
