Batch Item Modification ?

[benj9029]

Hey everyone,
currently working on a project that require around 1500+ items. Problem is that if I want them to be handy to use, I need to modify the placement parameter of them. Do you guys know about any tool that could modify those 1500+ items using a few clicks. I already find a way to optimize through openplanet so I just have to open and save items but it's still a huge amout of work.
