There are plenty of ways of doing this. My preference would be to write the whole thing out with no repeats. That usually results in the best sight-reading performance. If you MUST repeat everything that repeats, you will have a very complex road map, possibly containing two DSs. A slight modification involves writing out A3 and results in the attached example. I think the "alternate coda" is fairly self explanatory. Don't count on anyone reading your rehearsal notes.
