Pre-defined basic template layouts

I know we already have basic template mixs that can be tweaked but how about pre-defined basic templates where the only things changed are borders, layouts, fonts etc. Yes we can change these ourselves but it would be nice to have a visual display already configured for different styles of blocks, cards, fonts, etc. A mix will have about 20 sections, header, blocks, fonts, cards, body, etc....imagine if each section had a simple checklist of 1-5 pre-determined configurations that could be checked off. Want blocks to have round borders? Just check off rounded border option and all the blocks will be defaulted to rounded borders. Want your Fonts to be a single font style check the box and all fonts will be converted to that default style. If users wanted to go in deeper later and change stuff they still could later on
