Yup, had this exact gripe with the templating mechanics, so what I’ve been doing from day one is going for the “paste data into table” option while creating a new table, then pasting a single character that’s not a whitespace and confirming the “smart” headers detection. This leaves you with a blank slate that you’re after in two clicks and just as many seconds, so it’s definitely faster than deleting the scaffolded fields one by one.
