Is there any way flash when certain target out of combat

[SlivaNilow]

Hi
there is 2 macro
/cast [@ arena1] Sap
and
/cast [@ arena2] Sap

Is there a way to make one of them flash if one of the targets is out of combat, and both if both are out of combat?

or if combat status not available do next
flash then current sap debuff expired
i cant split flash by 2 target.. they flash both
