As far as I know, port naming is build-in into AUTOSAR toolbox and can not be configured or changed.
This is more or less becuase of naming convention of AUTOSAR architecture. If you generate a C- template file for your SWC from authoring tool, then generated port APIs are similar name_of_port_<name_of_variable>_<read|write>.
But good thing is, the exact names are required at root level only. We can change the port names at lower hierarchy (for example inside runnable).
In my case, I use scripts to import the arxml. And after the model is created script modifies the port names in lower hierarchy (not at root level) to short names like "name_of_variable". Thses ports with short names are used further for logic implementation.
