I am working with a small team designing a complex logical circuit using Proteus like this:
Each member designs sub-circuits and then we connect them together. The problem is that every sub-circuit is designed in a different file so then we want to copy the sub-circuit and paste it in the final design we are creating, but when we do that the sub-circuit is copied but not the circuit that is inside it, I mean, only the symbol of the sub-circuit is copied but the internal circuit is not copied.
How we can copy the entire sub-circuit? I tried copying the circuit inside the sub-circuit but then we have problems like duplicate references (U20 already exists, etc)
