Bring the Event Registration Refnum into the API (using a Register For Events standard function)?

[Arrowin-87]

The following accessor VI's are automatically generated for a gRPC service class (server side):
Read/Write Server Internal UEs.vi
Read/Write Server RPC Methods.vi
Read Server Stop.vi (generic VI part of ServiceBase.lvclass)

This is good but still lacks the user event registration automatically using a Register For Events call and output the Event Registration Refnum.
We still have to issue the following code if we want to integrate the registration of these user events into our own code every time (e.g. using this in separate actors serving a single 'service'):

Is it possible to create an override VI for this from the gRPC code generator (based on a parent VI "Register Service User Events" as part of the ServiceBase.lvclass for example) and outputs the registration refnum?
(I am not sure if a 'generic' Event Registration Refnum can be outputted?)

Is the desire to have a reusable block of code for generating the event registration refnum or is the desire to be able to customize the underlying data type for the event registration refnum by a child class? If it is the latter, then I do not think this is achievable in LV since the refnum type is strongly typed and there is no generic base type it can be cast to. If it is the former, you should be able to do that by constructing a typedef for the refnum type so that any changes made to the gRPC API over time are able to propagate through VI connector pane boundaries. You should be able to add this manually to the class after code generation, but I understand you would prefer the code generator do it for you. You would have to add the API to the leaf class though and not as an overridable method on the base class.
