# Situation
Sometimes you want to
* make the same change in multiple files
* or a change affects multiple different locations
it would be nice to indicate that certain changes are related
# Possible solution
This could be indicated via a new code fence info string attribute
````markdown
```suggestion:+0-0 group=use-this-class-and-import-it
import MyClass from 'src/MyClass'
```
…
```suggestion:+0-0 group=use-this-class-and-import-it
myClass = new MyClass
```
````
The UI needs to indicate that the suggestion is part of a group and offer to apply them all together
Furthermore, the UI could offer a view to show all the suggestions of one group together (maybe the new right-hand drawer? :thinking:)
