Need advice automating 5 video clips creation

I've been using Final Cut Pro X to create some video clips

The first video plays and has a title, it loops once

Then this video is made less than 25% the screen size
Below it, there is 4 further videos - each less than 12.5% of the original
On the right hand side there is text

I've created 70+ videos of the above, all the same, except the first video - which is different

Is there anyway of automating this?
I've asked in Final Cut forums and the answer is I can't

Just wanted to know if there was anything else

I can only work on my Mac - my PC laptop, if I could use, would take forever to process

Thanks
