The (dormant?) StickyNotes mod uses invisible constant-combinators that get auto-placed with each note to store custom text in blueprints. This idea could be adapted for the storage network to store interface and storage-to-logistic chest settings (one item-signal per request slot) and storage chest settings (a virtual signal for the read-only flag).
An alternative would be to actually auto-place a visible constant-combinator entity on top of chests that request from the storage network and use its signals instead of the current custom gui. That would also have the advantage to display the signals in alt-view and when hovering the mouse over the combinator. The downside to this could be a diminished user-experience. The hover area to hit the chest with the mouse could be to narrow, so wires might erroneously get connected to the combinator instead of the chest and it could be harder to open the chest inventory.
