Tying notes at end of Repeat section to notes at start; or across a volta

In the attached score, I'd like to tie the three-note Cma9 chord at the very end of the last measure of the repeated section to the same three-note chord at the start of the first measure. Any way to do this? It would be great if it worked both for notation and playback; but at least for notation.

I have the same issue sometimes with tying a note across a volta to the corresponding note in the second ending.

Thanks.
