LIGHTROOM - Import / Add with folder split

I think a neat feature would be when you import / add files to Lightroom that you can set it to limit the import to 100 files per folder or create new folders based on CD or DVD size for easy backup.

Example:
Import 500 files, it would split them into 10 folders
Event ->
- 1
- 2
- 3
- 4
- 5

Or you import a 4GB card that is full it would take it and do
Event - >
- CD1
- CD2
- CD3
- CD4
- CD5
- CD6

This would save me many headaches when having to split camera files up for burning CD's.
