Feature Request: Turn Into... All Highlighted Content

[jaizon2000]

Describe your feature request

When highlighting content, a user would be able to (let's say) convert H1 -> H2

What problem does this feature solve? [optional]

This makes it more efficient and faster to edit markdown files

Additional context [optional]

Here's a gif below of me trying to do it.

Do you want to set all of the selected text to H2, or only the parts that are already H1?

It should change all highlighted parts regardless of what type of line it is.

Is this different from the current effect of the menu item for header levels?

[Jocs]

The front menu is only for one paragraph. Is there any other interaction possible to change the heading level of multiple paragraphs at the same time?
