[Scripting Question] Sending excess items to the PC?

[Arachnee]

"A slot in the Bag can only hold a maximum of 99 of an item (by default), if you attempt to give the player more than this amount, the excess will start filling up a new slot. For example, if the player has 97 Potions and the game gives them 5 more, 2 of the extra Potions will go into the existing slot and the other 3 will go into a new slot."--Pokemon Essensials Wiki


So, how can I send the excess items to the PC Item Storage instead? Does it work like sending a Pokemon to the PC when your party is full?
