Can a graphic be anchored to a line of text but be OUTSIDE the text frame?

The idea here is to have a symbol that helps the reader find key statements but I want it to be outside the text box. I know I could indent ALL the text to kind of fake the margin, but I already have indents going 7 levels deep on a book with a two-column page, so I'd rather not sacrifice space nor do I want to have to adjust all the indents for each tag to compensate. Is this something that can be done in FM, or am I asking too much here?
