Improvement

How would you describe the priority of this feature request

Medium

Please provide a clear description of problem this feature solves

I would like to pass custom user-defined configuration data for each input in the UI which could be accessed within custom tools. Currently, the --override field through aiq serve could only overrides values in the workflow's configuration not input, which limits the flexibility of user input behavior dynamically without hardcoding values. This makes it difficult to generalize or reuse tools across different contexts or users.

Describe your ideal solution

In the UI, expose a mechanism (form field, toggle, JSON editor, etc.) that lets users define or select additional parameters alongside the main input.

Ensure this custom config can be accessed inside tools.
