P3D v3 The way of compiling

Hi. When writing approaches in ADE I usually write them directly to an airport scenery AFCAD-file. Alternatively I open a stock airport, write the approaches and then import them to the AFCAD-file which gives me the same result in the end.

Now, if I don't want to include the written approaches in the AFCAD-file of an addon scenery, what is the best way to get them into the sim? In good old FS9 I used to compile the approaches only, an option not available for Prepar3d if I'm correct? A few addon sceneries give me problems after compiling their AFCAD-file, that's why I need another method of doing this.

Thanks in advance. Regards Niklas.
