Ok, i am working with DxDesigner as Schematic tool, you too i think.
I think you can setup your gates with the parts property. They must have one single input and output.
So you have an relay symbol, where you set the property "parts 4".
The supply/"coil" (i don't know the word for an solid state relay) is drawn on a seperate symbol, you have to link the two symbols with the hetero property.
The hetero property is the name of the two symbols.
In my case my busswitcher:
74xx3245.1
hetero=74xx3245, 74xx3245_p
parts=8
74xx3245_p.1
hetero=74xx3245, 74xx3245_p
parts=1 (you can delete this property, default is 1)
The two symbols must have equal properties PKG_TYPE and so on, otherwise the Packager won't pack them into a single REFDES.
On the right side you have some resistor arrays, do you set them up with the parts property?. I think they should be single gates then. With this method i can associate nets over my resistor networks without problems.
