Can you midi map Direct Thru / Enable deck ?

Hi

Title says it all really, can you midi map Direct Thru / Enable deck in Traktor ?

I found a way to swap between track deck, remix deck or live input.
But I want to play real vinyl through my audio 6 while still connected to traktor and with live input there is a noticeable gain reduction. (can this be prevented somehow maybe ?)

Is there anybody else here that mixes in real vinyl while doing timecode sets, how do you do it ?

Thanks

Reading up on Direct Thru seems to suggest there is still a gain reduction, so you might be better off using Multicore cables to route your turntables directly to the mixer.

Edit: RCA splitter cables should do the same job too.

Multicore cables allow you to switch between real vinyl and traktor by switching between line/phono right ?
I bought the audio 6 second hand without a multicore cable.
