Indent to here with right align tab
I'm typesetting a volume of correspondence. I would like to have the address set flush right with the text frame and the date immediately under it but aligned flush left with the beginning of the address:

In this instance, I've set the address with a right-align tab and the date with a manually adjusted tab to align beneath it. But I would like to somewhat automate this, as I can't manually adjust every instance.
What I had planned to do was to insert an "indent to here" marker at the beginning of the address line, but this doesn't work: for some reason, it forces the following text out of the bounds of the text frame:

This may be a bug or it may be a feature; either way, it doesn't work for what I need to do here. I feel like this should be fairly straightforward, but nothing I have tried works. Any tips or workarounds would be appreciated. I'm using the latest InDesign on a MacBook Pro.
All best,
Sudhaus
