as i recall when you selected always build then a link would take you to a page with the coding just for external islands as well as some brief notes on how to but you still had to work on the css tags because the style sheet was not declared.
now you need to grab the file in cache builders and kinda marry that with the template file.
the file for the option is still there and works
Okay stupid me because I have not used it in years.
In cp goto column layout where you set the order of display for islands at the far right column it is there now.
But do not forget to check the always build on the subject island,
