Yes, you are correct. SL doesn't have a method to mass import, and if it did, you would still need to handle each image individually. Even though there are some techniques that make it easy to duplicate lots of triggers in a hurry, you still have to modify each one individually. 

To improve control on mobiles, you might experiment with slowing things down, either a slower frame rate, a controllable seekbar, or multiple copies of each image.
