Smart Mailboxes on device for iOS and iPadOS?

Is there a way that we can bring smart mailboxes that exist on the macos Mail app and allow them to be created locally per device on iOS and iPadOS?

The only way that I am able to create like features from Gmail and Spark for sorting emails from multiple email accounts is to create my own smart folders and tailor with a ton of rules that I manually input myself. I have one for Promotions, another for News, and another for Financials, etc.

That is great, but I often check my email on iPhone and iPad, and I have no such way of doing that on those devices.

Has anyone heard of the feature coming, or is there some setting that I am missing?

(Please don't repost a link to the method of using mailboxes and rules through iCloud.com. That most certainly does not solve this issue.)
