Questions about bk commit template

Hi!

I'm trying to use the bk commit template to remind developers to add a
comment including the bug number they are fixing.

Is there a way to have some help text in the template which is not added
to the comment even if a developer forgets to trim the text? I want to
do something like this:

------o<-------------------------------------------------------
BUG#<your bug number>
WL#<worklog id>

> You must make sure to enter either a bug number or a reference to
> the feature design document. Also, please include a high-level
> description of the problem that is solved by this changeset, not
> just a technical description of the code that was changed.
-------->o------------------------------------------------------

and I want the text prefixed by '>' to be excluded from the changeset
comments automatically, even if the developer neglects to delete it.

Any way to do this?

cheers,
