Populate old match cards with the rating that was valid at the time the match was played

Would it be possible for you to create a functionality that displays players' ratings in a match card prevailing either at the time the game was played or at the start of the relevant season? For example, the match card for a hypothetical match played in December 2020 should show players' ratings either as of December 2020 or as of July 2020 (if that's defined as the start of the season). Historic grades would have be converted into ratings via the usual conversion formula, of course. I currently can't see such an option in the "Rating Shown on Matchcard" dropdown.

The system stores the players grades at the time it the match was entered. Perhaps it would possible to a add a function the populated these retrospectively.
