Search options by lane/your own customisation, in Champ select

I was thinking that for the search bar in champion select, you could for example, write 'top' or 'mid' etc. and it would list the champions that are genarally played there. I understand that a lot of champions can play a lot of different positions and it wouldn't have to be 100% accurate, but because I main top and play a lot of champions there. Looking through every champion I own can take a very long time, and searching by role is silly since so many different types of champions can play top.

On a second note, I would personally like it if you could search by a champions secondary role too. If i type 'tank' into the search bar, Volibear doesn't show up because his primary role is as a fighter, despite the fact that he can very well play the role of a tank. I'm not sure everyone would agree with this but if not, it's a thought

Lastly, a customise option for the seach bar would work really well. For example, you could create the tag 'tanky cc' and then add your champions of choice to the tag. That way, when you're in champ select, you can type in your keywords and choose from your personalised list of champions.

I hope this can be considered.

TL;DR I think the search bar in champ select could do with some more options for searching through your champions
