Can you accomplish your purpose using a Sheet Connector (the little diamond shape tool)? You can have different components on different page tabs and connect them by Edit name and Width.
No, the sheet connector is not what I intended.
Please understand that the "Uses" Connection that I propose shall not connect components physically by wires, but it shall connect components' software APIs logically.
Another example: Using this feature, a "Bootloader" Component would connect to its communication component (Let's say I2C) by a "Uses" connection visibly in the schematic.
I would highly appreciate such a clear visual representation of an API connection on the schematic. This increases readability and usability.
