Show only tracks in used in the current cycle

Please can we have a way of displaying only tracks that have content in the current cycle region.

As much as all the visibility options are useful really what I need most of the time is to hide the tracks I am currently not working on i.e aren’t in the current cycle and display the tracks that are. I spend a lot of time basically doing this manually but it could be automatic. So it may be useful to have a option that does this dynamically, i.e when the cycle changes the tracks show / hide accordingly.
