Editor presentation : new line in title

Hi
I would like to enter some long explanation before some radio button (enum) attribute.

e.g. It should look like this

"Do you have external code from OEM/ Open source.
Please notice that this attribute is very important
Blah Blah..."
- yes
- no
- N/A

I would like to add new lines in the presentation's title or enter some title presentation (like separator)

Is it possible?
