Sword attack series based of multiple mouse clicks?

If someone can set me off in the right direction regarding even what blueprint this is done in (anim or char)

I have a series of sword attack anims that I want to be activated on left mouse click. Basically you click, part 1 of the series plays, you then click that same button and part 2 of the series plays which is a different anim.

Where is that done? Anim graph? Char BP? AnimBP event graph?
Theres probably a little blending involved maybe a montage but I havent seen any Tuts anywhere relating to this

A detailed answer would obviously be great, but I think I can get it if someone can just set me off in the right direction. Thanks.
