Keep in mind that the report object is generated for each execution. Whenever you are creating a new execution, it is now completely independent of the previous sequence. It has its own report object as well. The main sequence no longer waits on this execution to finish. The report options determine how the name is generated for each file. You can change this to force a unique file name to be generated, but I still believe this is not going to behave in the way that you wish.
The only real way to keep the functionality of one test and have multiple reports is to modify the process model so that it either parses the data generated by the report generation steps and creates new files, or change the way the reports are generated through the process model. Both of th
ese tasks are not trivial and would require a bit of work.
Hope this helps!
