Change Bullet Points to Content Control Check Boxes?

Is it possible to make a document with pre-existing bullet points (or blank boxes made to be bulletpoints) into clickable content control check boxes?

Also I’m having difficulty using a find and replace macro to change blank square boxes to content control check boxes in a document I’m using. I don’t know if it has to do with the fact that maybe some of these boxes are amongst different fonts or if the find and replace tool has difficulty picking up symbols but everything I’ve tried hasn’t worked out.

I tried find and replace macros and it didn't work. I also tried regular find and replace and it didn't work
