Delay in sending command to slave possible?

I'm running with a lock and an elemental shaman. I have Chain Lightning and Seed of Corruption on the same key. What I would like to do is make sure that SoC hits the target first so that my chain lightning triggers it. CL has a 1.5 sec cast and SoC has a 2 sec cast. If I'm running with my Lock as my main, is it possible for keyclone to delay the passing of that command so that CL happens .5 sec later than normal? That would allow both spells to hit around the same time and CL should trigger SoC. From what I could tell, WoW macros don't support delay so wasn't sure if there was another way to do this. Thanks.

unfortunately i think it is against the rules according to Blizz. you might want to make it a two button press, where the first button press does nothing.

yeah you can't mess with timings just have

/castsequence [target=focustarget] reset=1 , ,Chain Lightning

and wait .5 secs before tapping that key a 2nd time
