Not sure I understand the question. Do you have 4 schematic sheets in the Project, each with the same circuit on it, just with different prefixes and you want to make a PCB with all 4 on it? Do you want to produce a PCB with 4 of the same circuit as in the screenshot but don't want to have to draw - or copy and paste then edit netnames - the same circuit 4 times? BTW: your schematic looks like you have shorted all the collectors (Q1, Q2, Q3, Q4, Q5 etc.) together to a net called 47vcc. If that is true then most of the gates will not work correctly. I suggest you check your net connectivity using the Schematic Design Manager (Design button in the left hand panel).

@andyfierman I don't think that they shorted, I've put this circuit into a simulator

@DeaSTL, If your screenshot is of a schematic in an EasyEDA project from which you want to make a PCB then the nodes I referred to - and several more - are shorted together. This simulation demonstrates why: [https://easyeda.com/andyfierman/joining-nodes-to-make-nets](https://easyeda.com/andyfierman/joining-nodes-to-make-nets)
