Is creating items on possible

Hello I am trying to test some things on my localhost for the 7.2.0 trinitycore.
Is it possible at this point to create custom items in the database or otherwise?
If so how?

If you were using 3.3.5a or 4.3.4 this can be done easily by using the item_template in the database to make what you want and the stats you want with each item but with 7.2.0 you cannot do this task as easy without editing the files in the client because the item_template is no more in 7.2.0 I would go in detail on how to edit the client files to complete this task but it is prohibited to do so on the forums. Unless there is something I missed that someone can add to it.
