Add item to container before deployment?

Is it possible?
I want edit contents of the campfire/furnace/etc. before deploying.

 

Do you mean when a player is depolying it or you using your plugin?

 

That's what I want.

 

Seek for a Hook like OnDeployablePlace in the docs or request it, and then use item.MoveToContainer(container) to move items to it.

 

I added feature for /remove which pushes out all contents from the StorageContainer deployables.
And I want deploy campfire (for example) without wood inside after removal.
