Creating poses for aim offset

Hi.
I have all kinds of combat animations, like sword attacks, axe attacks and so on.
However, I recently learned that if I wanted to make sure that my character aims the attack in the direction that the character is looking (rather than just waving it infront of the character regardless of the aim), I’m going to need to use the aim offset blueprint

My question is: so, if I want to be able to use aim offset, I need animations for each and every type of attack, looking up, down and forward?
Like, for example, if I want to be able to aim my sword attack, do I also need to have an animation asset pointing downwards, upwards and looking forward? Isn’t there some way to blend a different animation which uses the same skeleton, and then use it for the rest of my attack animations? Or alternatively, to somehow create a custom pose without having to actually get these aim poses for each and every type of attack?

Thanks
