A button to create template with canvas sizes, custom swatches, default font. easily selectable afterward

Upon creating a new file, there are plenty of template, but none are custom made.

I Always wanted the hability to create a custom template with canvas size, RGB or CMYK, multiple Canvas or not, bleed etc. Custom swatche for our brands colors and remove the one we never uses.

cherry on top would be to choose a default font. 

The hability to save / modify it or delete it, and of course find it in the New document window.

The hability to download community templates woud be great too.
