How would I create an inventory system? Not the graphics...

[RubbleRaider]

I am thinking about purchasing Naninovel -- i am a disappointed Tyranobuilder/Visual Novel Maker user.
How would I create an inventory system? Not the graphics...I have those.
Is this done through a third party system? Or is there something built-in to Nani?
Thank you!
