Hegemony team and players
I think I have an easy question. Every time I defeat a faction and completely take over their territory I always maximize all the supply lines including all mines, forts, and farms back to my empire. I always finagle my way through this process, kinda of blindly mixing and matching farms with cities with mines with forts to finally create a combination that maximizes all the resources. I've tried to look in the manual, but is there an easier way to plan this. I know each fort and city has a max number of supply hubs or points. Is there a way I can look at each city and actually plan how my supply matrix is going to be built. I realize I may be overlooking something obvious, I hope I'm not embarrassed by how simple the solution is. Thanks for any insight.

No, there's no planning feature like that. I remember noticing in that region that there was a lack of supply nodes compared to the number of mines available. You could try a self-contained network up there, with one or no supply routes back. Income is still collected, and it's not a high traffic area that needs to be able to feed an army.

Is this true Hegemony team? Is there really no way to easily see how many initial or potential supply nodes each city has?

Not sure if this is what you mean, so I apologise in advance if it looks like I'm calling you stupid.

When you mouse over one of your cities, on the tool tip there is a line of numbers, the last set with a little green icon will say something like 2/3, or 5/12 etc, those numbers are the Current/Maximum # of supply nodes.

Thank you gentlemen. I can't believe I didn't see it before. Thanks

Is there a method in editing the number of nodes for a city?

nope, its fixed (according to historical circumstances).
You can only increase the population via immigrant at citys with macedonien origin.
I think it is a challenge to work with the nodes you have.
More than one time you have to decide to connect to a mine or a farm or another city.
