Attributes of objects' occurences /missing feature.

I need to determine the local identifier of function object in process?

For example: The same operation has in one process identifier = 20, and in the other process has identifier = 60, but this is the same operation.

This identifiers should be assigned to an object occurrence but an object occurrences does not have attributes. There are indeed functions <objocc>. SetSequenceNumber (num), <objocc>. GetSequenceNumber (), but I do not know how to handle their display like attributes.

Does anyone have an idea how to solve or work around it?
