🚀 go-pugleaf

What I want to have is a setup, where the writer of a documentation just needs to select the "hint"-paragraph-style, and automatically gets a special symbol in the "room for sideheads" column. I know it has to be done somehow with the reference-pages, but how? When I create a frame on the reference page, I can just tell the para-style to use it above or below the current paragraph, but not aside. I somewhere heard, that if I create a textlayout on the reference page (eg my column layout), I can adjust the position of the image frame relative to the text frames, and then the image frame is placed correctly on the BodyPage. True? 
Help appreciated. 

Another question would be how to generally set up a template for someone who needs to incorporate graphics a lot into his documentation. I have set it up, that there is a paragraph style for graphics that need to rest in the "room for sideheads", and one para-style for graphics that go all over the entire page. Are there better ways to do this? 

thank you...
