Common changes for a group of cards

Hello Decko community,

is it possible to use CQL to create a group of cards and then rename a common tag in all cards to a different tag, or could a search-and-replace action be used to convert a string in the content of all cards?

So this would be a bulk editing or batch modification for a group of cards.

Is there a function in Decko for such operations or would an easy to use script be possible?
