I'm not sure of it, have heard of it tho.
But if you were to create a macro that sorted out your data for you.
There is, I'm sure of a way of running a macro on exit.
(I think running a macro on exit is normally for validation purposes, but
it's all the same)
You should search and repost if needed for "running a macro on exit" or
something similar.
hope you can find what you're looking for. I've discovered a need for this
in the past, so will look around to see if I can find anything. If I do, I'll
let you know
