Selecting source channels without having to add tracks

With a multitrack source - if i want to choose A1 and A2 only, and bring it into a 2 track sequence, i. can't select just those channels - it adds the same number of tracks as the source, and chooses extra channels to insert. I then have to delete those clips, and then delete the extra timeline.

I should be able see to just choose my source channels. It's really bizarre and something i know AVID editors despise.
