Is it possible to create a Half Plate with 14+Dex Mod in the Item Creator

Is it possible to create a Half Plate with 14+Dex Mod as a magic item in the DDB Item Creator? Or Half Plate -1 Armor, or something with a similar effect.

Make a magic item with the base item of breastplate, give it the variant tag, call it half-plate. It'll still be considered medium armor though. 

Okay, thanks. Little disappointing that you can't do negative armor modifiers :/

I have just tried to modify an Adamantine Breastplate. It works with a negative modifier.

Oh - If you modify a set of half-plate to give it a -1 modifier, you can do that. Just edit a +1 half-plate and put a -1 in the modifier section.
