[eadocX Support]

Interesting idea!
There is nothing in native eaDocX to help you, unless the ‘joining’ gateways have a different stereotype, which isn’t normal.
Best option is to write a little script which eaDocX can call to print ‘Gateway’ elements. That script could then look at the directions of the connectors coming into it, and decide what to print based on that.
