Is it possible to change a Block you used everywhere so everywhere change automatically when you change the original.

Is it possible to change a Block you used everywhere so everywhere change automatically when you change the original.

I made a Block with a Disclaimer that i want to use on profiles. ( because affiliates don't think i am one of them )

And i made a grammatical mistake. And i want to fix it.

20 profiles have the block, how can i change all the blocks at once please?

Thnks
