Display TFT ranked crest or choose displayed rank mode

Hi TFT community, I just promoted to Gold 4 (don't know if that means anything or whatnot), but I would like to see if the client could present my new TFT rank as the displayed crest in my profile and banners, since it is a higher rank than my solo queue rank (silver 4). Would it be possible to customize/choose which ranked mode i can display? Any feedback/or criticism to this idea is welcome!
