While I'm not saying you are wrong to put in a request for HKN features, I will say that it's likely to go unfilled. HKN has (had) its own forum for things such as this, but Freddie has stopped supporting HKN and therefore, most likely, won't be adding anything new.

However, I don't use HKN and what you're actually asking might be able to be accomplished w/o the need for a new feature. There are a few HKN gurus that wander these forums so, you might just have to be patient and see if they reply.
