Just based on the description you gave, I would recommend you create another workflow process that accepts whatever input you need to have in your process.
The steps would be like this:
(Create a New Workflow Project)
Setup Process component
Expose Workflow Tracking ID component
InsertorUpdateNewUserDIT component
DialogWorkflowComponent
Give the project the input line items you need to have mapped over to the ticket process
Publish this workflow
(Create a new integration library)
Create a web service caller generator component that looks at the web service of your workflow project (above)
(In your existing project, should be more of a feeder-type project)
File Upload component
DynamicClassRead component
For Each Element in Collection component
Web Service Caller integration component - this is created dynamically by publishing a workflow-type project that accepts input values (described above) and then, using an integration generator, create a web service caller generator that points to that published workflow. This component will call the workflow as many times as the For Each component hits it, and will create that many process tickets as well, because each time it hits the web service component, the first component in the target workflow is a Setup Process component.
It's not easy to explain in text, so i hope you got at least some ideas from this post - if you need help setting it up send me a PM and I'll be glad to do a quick webex to help.
Also - unless you absolutely need the task/timeout/etc capabilities of the Dialog Workflow component over the regular Web Form projects, the feeders are normally used as Web Forms and trigger the workflow-type projects with web service calls. What you have above could perhaps be migrated to a web form to give it a lighter footprint.
