In trying to work on a Hatz AI Workflow I noticed the variable_type of the input can not be changed once created. As they can be created in error it would be nice to ensure that this was available for change at any time. This is the error message received (The Hatz AI workflow platform does not allow variable_type to be changed on an existing user input via the update tool — it silently ignores the type change and keeps the original. Tis is a platform constraint).

Also, the ability to add Gemini 3 Pro Image (Nano Banana Pro) as a LLM selector option.

Also, ability to use agents as LLM selector options per step in the workflow generation process
