A 2° Crown to Complete Dex

I think it would be great if we get a crown by complete dex without mythics (just like happen in games) and a second crown (light blue crown ?) by complete 100% of dex. It's kinda frustrating complete FireRed & LeafGreen or any other game but i won't have my crown here because there's no way to get the last ones, even if in game we can get our diploma.

Example: Get Golden crown by complete 150 in FRLG and diamond crown by complete 151
