Feature Request: Add Dualcast as a buff in the list for red mage

[Theletha]

it would help a lot to have it in the list so i dont have to move the original buff frames

[Rukishou]

Alternatively as a diamond indicator like Leaden Fist for MNK

[Justsometimes]

I would like to suggest adding an subtle audio que on acquiring the buff! Think it would greatly help draw attention to it
