Conditional fields if text is present instead of specific text

Feature Request Summary: 

I want to use a text field as a condition, but I need to be able to select "if text is present". Currently I have to enter a specific string to use as the condition, but that is too restrictive. I just need to know if there is any text in that field, and if so, I want to consider the condition met

Description/Use Cases: 

We have an optional text field that, depending on if it was filled out or not, would dictate if I show a subsequent field to my agents. However, I don't care what the value of the field is, I just want to show my agents the next field if there is any text in this field, not a particular string.

Business impact of limitation or missing feature:

I can't leverage conditional fields in this situation so my view of fields for my agents is more confusing because I always have to be showing the 2nd field, even if it doesn't apply at all to them.
