Dynamic "if value is" field for conditional ticket fields

Is it possible to make dynamic the "If value is" field for the condition? For example using regular expressions? This would be helpful for cases where a field can take any text value from the user and we might want to recognize certain patterns. If not, it would at least be nice to check if the field had any value at all rather than having to be a specific, exact value.

It was suggested to post this here from https://support.zendesk.com/hc/en-us/articles/4408834799770-Creating-conditional-ticket-fields 

Thank you,
