Can the contact information and saving method be changed？

Could you change the online connection method? Currently, I can only play on the same network, which prevents me from playing with friends in different regions. Could you add save IDs so friends can simply enter their save IDs to join the game and play online together? Also, I'd like to add a Steam linking feature to sync saves between PC and mobile. I hope this will make it more convenient for players to sync saves across Switch, mobile, PC, and tablet. After all, I don't want to start over before finishing a save, and I want to be able to play anytime, anywhere. I hope the game continues to improve.
