I created a frame using the rectange frame tool and copy/pasted it hundreds of times throughout a document for use as a "checkbox" in the printed version of the document. Now I want to convert that document to an interactive form (PDF). I turned one of the frames into a "Frame (form field)" by using Object > Interactive > Convert to Checkbox and then modified the size, color, and positioning of the check mark to my liking. How do I most easily replace all the frames with my custom checkbox frame? I'm using Adobe InDesign 2021.
