At 10.2.1, you need to work on each element, i.e. input/output connector box, at GeoEvent Processor Manager separately to modify its shape. In other words, there is no easy way to unify those box shapes at 10.2.1 if you have lots of them. You can move them at the same time, but not change the shape.
Prior to 10.2 at a Service Designer, you can modify the shape by capturing all your target elements at once with a selection rectangle around all of them.
This function is no longer available at 10.2.1.
I'll be appreciated if this feature gets back at near future update in terms of realizing user-friendly interface.
