Using sticky feilds after a deck is created. HELP!

Hi, I have been struggling with this for a few days. I can’t find any answers, please help!

Once I have created a deck all I want to do is edit a feild in one card and have that edited feild apply to all cards in the deck or tag. how can i do this? I know there are stiky feilds when you are adding cards inside anki but after a deck is created and you are editing the feilds individually i want to know how to get the same result.

You can go to Browser > Find and replace command (limited to an specific field).
