Balancing of storage or...how to get item X to place Y to build and maintain

[Roversword]

Hi all

I likely miss something, however, I going to ask anyway.

I have three drone hubs in a row to cover a big area...two of them share some area (the first one with the second one and the second one with the third one).

In each area I have a general/default storage and also one general storage in the overlapping area.

Now, I have a windmill that needs machine parts in the third hubs area...and all the machine parts are in the first hubs area....
How do I make sure (without micromanagement the transport rover) that the machine parts (and all other items for that matter) somehow get balanced out in all areas and on all storages?

I believe that, as long as there is a depot accessible to both the first and second drone hubs, and a depot accessible to both the second and third drone hubs, resources will be shuffled from place to place as needed.
