Final Fantasy Hacktics

Thanks, man.

My problem is on the PSP version of the game. I want to add the items on the left side, but it doesn't show me the cities or shops.

Here is want I mean.

I want to make some items available in the shops. I can do it with the normal items, but I want to add the extra rare ones, like the chaosbringer. It doesn't give me the option to do that. What can I do?
