Suggestion for more formations

Hi EA FCM team, I send my greetings

My suggestion is somewhat simple; I'll like to know if we can get more formations added with the next update or subsequent updates. I'm particular about the 3-4-2-1 formation which was excellent for my gameplay 2 seasons ago but was removed to my surprise 

As a side comment, would a custom formation edit be a feasible feature soon? I wouldn't think that's so much technical challenge for mobile devices to process but I only know so much

With that said, I'm rooting for the team and an excellent job done so far. Looking forward to the season update on Thursday, can't wait

Cheers
