It is possible - you can use the flash manager option in the content block - just expand the designer ( click on More formatting options ) and browse to your .swf file. Please note you have to create a folder Files in your root directory where your .swf files are going to be uploaded. You will also need to allow the FileManager to accept larger files ( settings -> advanced -> system -> FilesModule ). I have created a video which demonstrates the procedure. Find it in the attached archive.
