There is not such order, is there? It is within the event itself, a unit starts the effect of an ability. If a unit is ordered to target an object, it will be the most common i guess, attack/healon/unimmolation/smart/stop and so on. Unless you want it for "Order unit to cast spell"; well, the spells you can have are selectable already within the order unit to Neutral - Firebolt for example.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
