Different ending for a Vamp?

I have a vamp whose very last repetition should be different, and I’m wondering how to notate it.

Initially I thought of using “repeating ending” but I can’t figure out how to communicate that the Vamp could repeat many times and it’s only the last time that the alternative ending should be used. The numbers 1 & 2 seems to be misleading for that.

Any ideas?

Something like this maybe?

How do you write custom text on the Vamp? I couldn’t figure it out.

In Engrave mode

Thanks! I didn’t realize I need to be in Engrave mode for this. Especially since other properties are usually available in Write mode.

This should indeed really be in Write Mode…
