Ability to indent macros (panels, code blocks, etc)

I'm trying to use macros like panels, code blocks, etc, within bulleted lists. However, even when I style them to be indented to match their parent list item, they do not render as indented on the saved page. (They're always aligned to the left-most edge of the page, and ignore the indentation I've given them.)

Is there not a way to specify an indent amount (or border-left CSS property) for the macros? If not, can this be added (or is there a workaround through other markups)?

Thanks for the assistance.
