Get package name/ID in the Log method from an SSIS Custom Logging Provider

Get package name/ID in the Log method from an SSIS Custom Logging Provider

I have a custom SSIS logging provider to push logs from SSIS processes to
a custom logging service. The logging configuration is in the package
level.
Process: 1. In the OpenLog, I create an operation ID to the log, to be
assigned to the existing logging service. 2. When the log method is
executed, I log an event in the existing logging service as a child of the
operation created in the OpenLog method.
Everything works fine, however a new SSIS package was created with child
packages. Therefore, now I have multiple Operation ID's, and since the
packages are executed in parallel, I have to use the proper Operation ID
to each log.
Problem? The Log method doesn't provide the current package. The SourceID
provides the component ID, but not the Package ID.
Is there a way (from the API) to retrieve the package logging an entry?
Thanks, Rob
