Change topic type / add custom type
It appears that the list of topic types (announcement, idea, problem, thanks etc) can't be amended, other than to add or remove.
Is there a way to change the title of a type, or add a custom type?
The types are almost perfect for us, but we're also keen to record positive feedback - it's sometimes as useful to hear what's working well as it is to know what can be improved.
('Thanks' is the closest, but it's not quite the same.)
