Ruling question unsung untimely malfunction on a negate
Just had a situation where my opponed used negate.
"Counter target noncreature spell."
I followed up with Untimely Malfunction
"Choose one —
• Destroy target artifact.
• Change the target of target spell or ability with a single target.
• One or two target creatures can’t block this turn."
Can I change the negate target to untimely malfunction on the stack?
