How to define an xmmword variable in IDA? enter image description here

IDA identified one variable as xmmword but I can't find a menu to define other variables around it as xmmwords: enter image description here

I also tried to set the type after pressing Y key, and set it as xmmword, and also tried to set the strtuct type after pressing Alt+Q keys, but there is no xmmword in neither of those 2.
