Add text and icon to polygon (path) annotation

Is there an (easy) way to add a text and a small icon to a polygon annotation?
I'm adding a path with AddAnnotPolygon() to a pdf page and I also want to a a single line text and a small icon into the annotation.
Is this possible? Or do i have to draw each element as a single annotation??

Or is there a way to tag or to group the annotations from stack?

yes, seems you need add 2 annotations on page.

Is there then any way to remove an annotation without rerendering oder just rerender the small section where the annotation was?
Asyncredender let the page flicker und renders the complete page.
Syncrender is not working for me.?!
