Tracking-Black Out Help Needed

Here's a simplified example of my question...

Let's say I record channels 1-5 @ full into Cue 1.

I take channels 1-5 to 0 and record my black out to Cue 2.

I decide that I want channel 6 @ full back in Cue 1.

Channel 6 now tracks into my black out Cue 2.

When I'm recording a "Black Out" cue, is there a way to keep changes to prior cues from tracking into the black out cue?

Thx.
