Can't freeze with drum track-workaround?

I’ve been trying my hand with the drum track feeding several instrument tracks for my drums. Now that I have gotten used to the drum track I like it, but as is usually the case, as my projects get up past 100-150 tracks I start needing to freeze things in order to have everything play back ok. But now I’m seeing that I can’t individually freeze instruments that are being fed by the drum track.

Anyone have a work around for this? The best I can see is to explode the drum track in to individual tracks and then drag the midi to each respective instrument and freeze but that defeats the purpose of using the drum track in the first place.
