Savings account

Would it be possible to create a savings/interest account for major or all altcoins supported by trust? That way when the coins pump, we can shave and save them in the interest account instead of watching it all go up only to fall back down without doing anything?
I believe it would be a very wonderful improvement for the wallet

Can I get a second opinion on this issue?
