Jerry, I was sleeping as Box said. Now I’m waiting for my coffee. 
I went back and found the thing you are referring to although I’m not real clear on what part you want to change. You could make a component of the part and give it gluing attribute so it would glue to any face. Also set the component’s origin at a logical point. The origin becomes its insertion point when you drag it in from the Components library. With the insertion point and gluing, you would be able to bring the component in and quickly drop it where you need it.
It would be helpful to have more visuals of what you are trying to do with the tab now. Is the angle you talk about variable over a wide range or is it just a couple or three different angles you need?
