Backwards ties at start of 2nd x bar

I’ve been faking backwards ties at the start of 2nd time bars with laissez marks.
Now I need both a backwards tie and a backwards slur on the same note.
Any ideas?

I guess you could add a slur, and then move both of its end points in Engrave mode so that it starts and ends earlier than its actual position.

Yes, of course. I think I’m asleep…
