It would be nice if PCANPOL could be used in the description of the custom field and on the bottom of the booking widget. I have a custom field "Initial to acknowledge the cancellation policy," but the text is hardcoded. If the cancellation policy varies by season or property, that won't work. If the field is dynamic based on the property/dates selected, and can be inserted in the widget & custom field description, it would be helpful.
I submitted something similar, they need to increase the places you can use Custom Field Definitions. It would make them way more powerful.
