Find a layer containing a certain number or word?

Hi,
V5
with over 300 layers and many with IMG_12345 etc numbering, I need to find a layer with a certain number in it or word.

I see the raster I need to work with in my file explorer to to read through all the layers is a pain.

I dont suppose for one minute there is also a way of scanning for such in all my Rhino files in their folder ?

I had wanted this many moons ago, but nothing came of it.

Is it possible with a code or something ?

Can V8 do it, as it was put forward for inclusion in V6 !

Cheers

Steve

V8 has a search bar at the top of the layers panel.
