Working with differents schematics

Yes, im working with Block Diagram/Schematic. You say that generate a Top Module that includes many others smalls modules in it?. And after that , open another schematic and start including all different modules to be connected?

What i was trying to do , is , to have different schematic with a lot of modules, and interconnect different schematic by some port... is like some CAD software do for instance Altium, yo can use different schematic, and interconnect them, instead of having a big sheet schematic with several different modules.

Thank you so much.
