Unable to Add Common Node After Switch Node in Oracle Fusion AI Agent Studio

Summary: I am currently designing a Custom Workflow agent in Oracle Fusion AI Agent Studio for an invoice inquiry use case.

My flow structure is as follows:

• LLM Node: Extract Structured User Input
• Code Node: Determine Search Identifier
• Switch Node: Route by Search Identifier
• Multiple branches based on identifier:
  • Invoice Number
  • Supplier Number
  • Supplier Name
  • PO Number
  • Invalid Input

Within each branch, I am:

• Calling the appropriate Business Object Function (REST API)
• Adding a Code Node to determine the result type (single, multiple, no result)

Issue:

After the Switch node, I would like to add a common/shared node (for example, for response formatting or unified post-processing) that all branches can connect to.
