Easier adding to Blocklist

Is there an easier way to block unwanted spam? I receive 3-500 spam messages per day, and though they are going to my spam folder, I spend a lot of time checking them for false-positives. The only method seems to be adding to the Blocklist manually, one by one in settings. Maybe I missed it, so forgive me, I’m new. It seems that if there’s a Ctrl+Cmd+S for marking spam, a Ctrl+Cmd+G for marking good, why not a Ctrl+Cmd+B for blocking?

Thanks for any help on this.

Training as spam also adds them to the blocklist. You could also set up the Block Sender script for the rare case of wanting to have a keyboard shortcut for adding to the blocklist without training as spam.
