Does the gutter support markers that extends to multiple lines?

I was wondering if the gutter can support markers that span multiple lines. The use case I am considering is gutters that show visual indication of decorations that span multiple lines or gutters that shows changes as in IntelliJ IDE

In terms of DOM structure, markers are per-line (they are children of a gutter element for a specific line). Possibly with some absolute positioning and creative sizing, you can make things look like they cover multiple lines.
