Combine the properties of 2 spells?

[Scippi]

What i mean is like say if i combine chain lightning + forked lightning together 4 units in a line will be hit by chain lightning then the lightning will branch out and hit the units behind each of them

Have dummy units cast spells with triggers. Done.

It's not only about the dummies,i think the whole spell must be triggered because you can't detect targets of forked lightning from which another lightning will come out.
