Citation key generator gives no date for InCollection with crossref

The citation key generator gives no date in the key for In-* entries which get the date value from a crossref. I need to manually add the date to the entry to get an [Author][Date] citation key.

Is there a way to have the generator pull the [Date] value from the crossref entry.
Something like :
[Author][Date:From-Mary99]

I would suggest to open an issue at github, as I think this would require changes to JabRef’s code.

MIght potentially be covered by crossref workflow improvements · Issue #6294 · JabRef/jabref · GitHub, but please open a new issue, which then can be referenced in 6294
