Can I have an overall rank?

Edit: Or, find a way to cater to fill mains? Maybe make the lp splash more effective if you voluntarily select fill?

I'm a fill main and it's taking sooooooo long to climb at all (I'm on an 11 game win streak). Each of my lane ranks are the same and it is becoming such a chore to try and climb. I mostly get jg/support and rarely get mid/bot so my mid/bot ranks are taking so long to get anywhere. I just want an overall rank again like it used to be :'(.
