About the pokemon unite treasure chest challenge

Can we perchance get an option to save the treasure chest tickets and also expand the date to when events leave. Like the skins look really beautiful and its a shame how it always asks way too much especially with the luck rate, I feel like that event is kind of not fair for F2P players because they cant spend hundreds of dollars just to keep opening chests until you get the holowear, and every event causing pokemon outfits/trainer outfits all have such a small date to clomplete? there are people out there who arent stuck on a game 24/7 so theres really no chance of finishing up such small dated events.
