Roster Design - Favourite Teams


I'm sure it was suggested in the past, but I'd love if devs would consider implementing the following feature.

Particularly for PvE purposes, I have favourite characters in my roster - like everybody else. However, due to the sky-high number of characters available, it can be hard to locate them in my roster each time I enter a match.

What if you could select heroes and add them to a favourites' list, much like the Shards' Favourites, so that these said characters are available in the first page of our roster?

Or - going out on a limb here - what if we could choose a certain number of favourite team sets of 3 characters to be picked?
