That won't solve anything. Congress already has this power they just abdicated it to the Executive. The only fix is better voters electing better people into Congress. -- good luck with both of those. The US is cooked.
Congress moves a lot slower, though. Congress isn't going to change tariffs every 24 hours. It takes a lot longer to get anything through Congress.
I mean, you still have the "every 4 years", or worse, "every few months". It's not at the pace that Trump changes things, though.
No, it’s not good enough, you need a better system. Like in Switzerland
