With a custom button, how do I validate multiple input fields before creating entry?

I have a create action connected to a button. The action pulls in data from multiple form fields.

The problem I am having is that “This action will only happen if…” appears to limit me to one condition. I need if input1 is not empty and input 2 is not empty: create entry

Unfortunately, this functionality is limited to only a single filter at this moment.

A workaround that I often use for this is to have 2 buttons, each with different visibility settings that accommodate each scenario for the condition being met.

It’s not a workaround that is usable in every circumstance but it’s the best that can be achieved at this time.
