Global Stylesheet

Hello,

Is there a way to add a global stylesheet to all the email templates? Right now I’m adding the same styles to the “custom css” tab, but every time something changes, I have to modify ALL the templates one by one….

Please let me know if there’s a workaround.

Also, are the blocks “dynamic” or do they stay the same as when they were inserted into the templates. IE if I modify the blocks, do the templates containing the blocks also update to the modification?
