That's what names are for. If you name the terminals, you can

For a capacitor (and most basic 2-terminal devices) "p" and "n",
as per the Verilog-AMS spec.

There is a method "port_name" that returns the names of the
ports. It takes an int argument, as if it is indexing an
array.
You could edit the code. You can make a modified version and
use it as a plugin.
