FEATURE REQUEST! - Ability to only lock clips to their corresponding tracks

Hi, I would like to reques the following feature. 

The ability to lock clips to their corresponding tracks without losing any editing capabilities. 

For example, after dragging clips to your timeline, once you enable this feature, all clips are locked to their corresponding tracks however, you still have all the editing capabilities as normal, so only you can't accidently move clips from one track to a different track by accident. 

Meaning, you can edit your timeline as usually, only all the audio tracks on track 01 can't be moved to track 02 or track 03 by accident, they can only be moved to other spots on track 01. And all other editing features are still available. 

Thank you
