I don't suppose there's a way to make Visio give you symbol definitions in Crows Foot diagrams?
Rather, I think it would be nice if you could hover over a symbol and have a definition float over that says "Many or 1" or something like that based on the symbol you are using. That would be useful for people who like me are learning the notation but also people who aren't as technical who need to understand the diagrams as well.
