Possible to Annotate my Events Log in Radio?

A method for annotating and archiving my Events log would, I think, shed light on my iterative editorial process and acknowledge the effort (in the sense of crossing out items on a to-do list). Otherwise, I just cringe at old posts with typos and sentence fragments, shrug, and then move on.
I know I could remember to copy and text-massage the log every night, but knowing myself as I do, that won’t work.
