Ultimate Team improvement

The idea with live substitution in CLUBS matches is great. Can you also add LOCK option on players in Ultimate Team. I put my Gold Rare player who I was upgrading in Evolutions into an SBC by mistake. You can also add put favorite pack first option or something. I have like 100s of PACKs and when I want to open for example 78+ player pack I have to go through 50 packs. This improvement will save a lot of time and effort.
