Help with Combing Macros for Hellfire (Warlock)

[WildcatTM]

Greetings, folks,

I need help combining 2 useful macros for Hellfire into one. Basically, what I want to do is to set up button 1 (left click) to cast Hellfire and if I press it again I would like to cancel the Hellfire aura, but when I press button 2 (right click), it goes into Meta and cast Hellfire.

This macro works perfectly fine that toggles the Hellfire on/off:

Macro 1:
#showtooltip Hellfire
/cancelaura [channeling] Hellfire
/stopmacro [channeling]
/cast Hellfire
/script UIErrorsFrame:Clear()

This macro below is the button 1/button 2 macro, but no toggle:

Macro 2:
#showtooltip Hellfire
/console Sound_EnableSFX 0
/cast [nomod, button:1] Hellfire
/cast [nomod, button:2] Metamorphosis
/cast Hellfire
/script UIErrorsFrame:Clear()
/console Sound_EnableSFX 1
