Is possible to manage a "global reference id", therefore all process h

Yes, I know that amirula. But i want to a new "global id", that all process can reference it in the reports, to make a general portal report for all instance process.
For example: Process Name - Start Date - "Global ID" - etc...

This "global id" is a pesonalizable variable that i have to initialize at the beginning of the processes in the model, and then show in the portal reports for all process.
