Did it. Pretty simple to do. However, every time you publish you have to redo the steps.
- Create interaction A
- Create interaction B
- Insert swf from A.
- Publish.
- Copy engage_content folder of A and paste inside engage_content folder B
- Inside engage_content folder B is a swf (mine was swf0.swf) that represents the inserted swf media from A. Change the engage_content folder for A name to swf0_content.
- It should work.
