Dynamic queue swap role and fill counter

Hello, I just got two simple ideas. Here they are:

1.) Wouldn't it be great if there was a button in the champion select for the role swap? I mean, you surely know this. You get into champion select and someone asks you whether they can swap their role with you. Instead of writing this into chat, there could be a button for the role swap, similar to the one for champion swap.

2.) This regards diamond+ players. You are surely familiar with the autofill and the system that makes sure you won't get autofilled if you have filled in the last few games. Wouldn't it be nice if there was a counter of how many games you have filled voluntarily? Let's say, that I set my role to fill. Now, everytime I get filled, the counter would increase it's value by one. I do this 5 times, the counter is gonna hold the value of 5. Then I catch the adc mood. So i setup, lets say, adc/mid. It would be great if I was guaranteed to get one of those roles at least the number of times I voluntarily filled, so in the example case I could be absolutely sure that i am gonna get adc/mid at least 5 times in a row, as I have "collected" the fills.
