Index Date Format?

[simbun]

I'm not entirely sure I follow as the attached image doesn't reflect your indexDate and looks more like an album listing, but I'll try and answer your questions and if I've misunderstood anything just let me know.

If you're asking to add it to the indexFormat then:
$date^Release Date: ^

To only display YYYY in indexes, you'd use the tagOption:
tagOptions: Date.yearOnly.index
