Well, there are two ways to do this:
1) Create a template drawings with two views (flat pattern and side view).
Create a makro button in sheet metal part interface on one of the ribbon tabs.
Use this button to open the template, replace the part reference to the currently open part and save it under new name (auto/man).
This one has an advantage: You can have some dimensions already in place and they will be (mostly) preserved as you create new drawings.
2) Create a makro/rule in drawing that every time you place a flatted view it will place a side view right next to it.
I already have the code for 1), so I'll just have to slightly modify it.
The second option would have to be made from scratch.
I can look on it later if I'll have some time, so let me know which you prefer.
