Currently when emails are grouped, the email in the inbox shows the first label of any email in that group, based on the custom sorting of the labels. Instead I want the labels to only reflect this particular email, not its group.

As an example: For some services I have multiple accounts. These accounts use different email addresses, which automatically apply a label for each address:

Address A => Label A
Address B => Label B
Address C => Label C

If the latest email was sent to address C and was labelled Label C, it shows as Label A in the inbox if any of the previous emails in that group were labelled Label A, or Label B if any of the previous emails in that group were labelled Label B. Instead it should show Label C, because realistically that's what it is.
