We need better storage management in the game. It can be an essential requirement in the late game with large sprawling towns. Whilst it is currently possible to move a specific item stack from one storage building to another specific storage building, it is an overly complicated process that involves unticking/unchecking the item you want to move in all relevant storage buildings between the source building and the required destination. Eventually the labourers will deliver it.
What we need is to be able to move a specific qty of an item from one specified storage to another.
This feature is already in the game with animals. We can move a specific qty of cattle to a new named barn for example.
So I propose you auto-assign each newly built storage building a unique name or number (with an option for players to add custom names). When we click on a stack of items in any storage we are presented the option to “move items” with a qty slider and a drop down menu listing all suitable named storage destinations to choose from.
