RPG Maker 2k9 Ultimate question

So, I'm currently using 2k9 for the added benefit of additional slots and whatnot. However, I noticed when I was going to copy/paste stuff in my Items database to slots 5001 on up, it does not allow this. Is there any way to deal with this other than manually putting everything in past slot 5000, or am I stuck doing it this way? I ask this because I have a lot of copy/pasting to still do (only did copy/paste roughly 2000 times for weapons alone for Weapon Bless, and need to do quite a bit for Armor Elemental/Status Blesses as well) and it would be quite troublesome to have to do it that way (that, and would those slots still be working for those that don't use 2k9 on their computers as long as it's not touched in 2k3?

uh, 2k9?

Yes, 2k9. It's an extension to 2K3 made by Cherry, IIRC.

I figured it must have been something to that effect, I just was a bit curious.
