Open BIML script without losing format and intellisense

Case
A couple of months ago I posted some tips about getting started with BIML. If you mix C# and BIML then you could loose formatting and intellisense. You can overcome this by right clicking the BIML Script and select Open With... Then choose the XML (Text) Editor. Now it opens with formatting and intellisense. It works, but it's still a little annoying...

Open in XML (Text) Editor

Solution
There is an easier solution: move the imports to the bottom of your script. Now close the script and open it the normal way.
