The other thing you can do is make a popup that accepts a tag path and a value to write, then if the user clicks yes it will write the value to the tag. I’d create a library function to call the popo and pass your pat and value to it to standardise it.  
Unless you want to do more than just write to a tag, a message handler in this instance is a bit overkill imo, and takes slightly more work to implement, especially if you want to keep reusing the same confirmation popup for other things as well. it becomes less of a template and more of a manual process to follow
