Adding global damage modifier field to existing character sheets

Rather specific question, and I couldn't find exactly the right answer. Not sure if this has been answered yet. Plus member, using "D&D 5e by Roll20" for my character sheets.

I have already filled out PC character sheets that I want to add the global modifier fields to, such as global damage modifier, that are not currently available to the sheet. I've gone into the game settings, checked the boxes to allow them to the sheets. Unfortunately, this hasn't added them to the existing sheets. New character sheets have the options, but the ones created before hand do not. If I duplicate the character sheet, the "copy of" still does not have the fields attached.

I must be missing something. Is there some way to add that field to an existing PC character sheet?

Alternatively, Is there some way to copy in bulk data from one already filled out character sheet and paste that into a newly created empty character sheet?

I have several PCs to update, so I'd rather not have to redo them all from scratch onto new character sheets if I don't have to.

Thanks.

On a character sheet, you can go into the settings tab (it's the gear icon next to the SPELLS tab) to toggle on/off the global modifier fields for that sheet. You can copy completed character info by clicking the "Duplicate" button on the Edit tab, which will pass the data into a new sheet.

Thank you, this is exactly what I was looking for. Seems obvious once it's pointed out.
