Video collages - is there a way to use random transitions between pictures?

I'm putting together a video collage to commemorate my son's college graduation.  I see that you can apply the default transition or a select a specific transition to put between all of the photos in the collage.  But I suspect using the same transition will get boring so I'd like to use a variety of transitions.  However, there are a lot of pictures in this project and choosing a specific transition between every pair of pictures will be quite time consuming.  Is there a way to insert a random transition type between all of the pictures?

Thanks!
