text box affecting paragraph indents

The Author Robert Greene has quotations to the sides of his paragraphs in many of his books (see picture). When I try to do this, though, I cannot have paragraph indents on the left page like I can on the right page—if I do move over the tabs then it moves text on the right page so there is room for a text box to the left instead of the right. 

The only thing I have come to is using two em dashes in front of each paragraph and then coloring them white, which is time-consuming and makes further editing difficult. 

Also, the text boxes tend to move around on me when typing, or will be selected when copying text. I know I can lock them one at a time, but setting them up so they are in the same place on each page is time-consuming and annoying. 

Is there a way to make all this work together? Any help or further questions is greatly appreciated. Thank you.
