Thanks, Denny. that's perfect. Just to complete the question for the 
archives, you would call the no_wrapper like this:
$c->stash->{no_wrapper => 1};
$c->stash->{template} = 'account/display_account.tt2';

I don't know how to set the template.custom_wrapper, though. I ended up 
just using a variable in the stash called custom_wrapper and then 
deleting the 'template.' from the example above.

$c->stash->{custom_wrapper} = 'my_special_wrap.tt2';
