Bring up standard keyframe menu when "available" keyset is selected, but no keyframes are available

So here's the scenario, I like to enable automatic keyframing, but I only like to do it for the "available" keyset, ie, something I've already created some keyframes for. This works great, as I'm not accidently adding keyframes for the location of objects that I don't want to.

However, the problem comes when I DO want to subsequently add keyframes to an object. I press the "I" key to insert a keyframe and I get the message "No suitable context info for active keying set" ie, there aren't any keyframes yet. I think that a more suitable default (or at least something to make it as an option) is that this would automatically bring up the standard keyframe menu (as if you didn't have a keyset selected) that will let you choose which channel to add a keyframe to, since none already exist and you're obviously trying to add one.

Another option would be a way to separate the active keying set from auto keyframing and from key insertion menu.

Hopefully this all makes sense. Maybe it's not a problem for others, but I find it annoying!
