@carlw It's not needed. If you can write the code to do the cleanup, you could use the fragment approach right now. I'm onto something that manages all this behind the scenes though, so you don't even need to think about cleanup, and still would only have as many fragments as you have cells. Unfortunately, I've gotten a ton of work to deal with (we're moving in some large customers with lots of domains/emails/webs) so I'm stuck for some of the weekend with writing import routines etc. Hope to have time to finish this feature before the weekend though.
