Organising footage in a sequence - Two Layer Colour Coding

Hey, had an idea for a feature that I think could be really useful for alot of people scrubbing down big projects, and making the organising of footage more visual. 

I know there is already a feature to colour code clips, but, just one set of colours is generally never enough, as there are two main areas that people like to keep orgaised. 

1 - The type of shot (wide/close up/b-roll/talking head/subjet/details etc)

2 - The location of the shot in relation to the order the shoot (i.e exterior/room 1/room2/ location 1/location 2/day1 /day2 etc)

What im suggesting is keep the colour coding of the clips the same, but add another option to change the colour of the outline of a clip (adding a coloured stroke), so you can easily see the two colours signalling the clip is a "b-roll shot in the kitchen" without having to scrub over the clip. 

I feel like having two layers two the colour coding processs can be used in more ways than ive described so feel like it could be a handy feature that solves alot of other problems with organising too.

Just a thought! Would be a huge time saver for myself...

Thanks!
