Is your feature request related to a problem? Please describe.
The KaibanJS UI currently only supports single executions, meaning users must manually re-run the process for multiple inputs, such as processing a list of students.

Describe the solution you'd like
Enable support for multiple inputs in the UI, allowing batch processing and enhancing the workflow efficiency for users.

Describe alternatives you've considered
Maintaining the current single-input system and requiring users to create custom scripts for batch processing.

Additional context
This feature will improve usability for scenarios where users need to handle multiple items or inputs, making KaibanJS more efficient for larger projects.
