How can we change marking style on a bill already entered?

I entered 5 Sherlocked bills today. The closest option is not marked so i picked that but only change the first menu thinking that was enough. Nope it still says marked on back in black ink. oops didn't realize it until I entered all 5. Is there a way to change it?

I do not see how.
The only edit button you get on entered bills, only allows you to edit the actual bill note.

Go to "edit profile" on the selection screen for your reports. At the top, you will see "What marking style are you using for new bills", under that you will see a link for "Change marking styles of existing bills". You can change them in that screen. You will need to know what entry number they are and you can change the whole series in one swoop.

Thank you, Dave...for a better answer than mine!
