I did it once by accident. Using the Start/Stop effect primitive (same as with objects), run a "soft start effect" on the target "My Object ID" at "default 3/4 height". You don't need to create any custom slots or anything, sims come pre-slotted.
The rest is much the same.
If you want to subsequently stop the effect of course, you have to run the stop effect command at that time.
