Auto Site Detection / Preconfigured Sites to Chains / Auto Chain Detection

Hi Guys,
Would be great if we could have a saved list of sites and their respective chains

For example, when I go to - I will only ever always use the BSC Mainnet. I should be able to tell Metamask to always be on BSC Mainnet when I am on this site.

Better yet, just like I visit some sites and they detect I am on the wrong chain, MM should auto-select the correct chain if it detects a site is looking for a specific chain.
