Impulse theme variant image set if option 3 level

[nobleorchid]

Hi, 

I'm using impulse theme and created variant images sets with option 1&option2. 

I set color and size. And then I set alt text per images.

For example, "title#color_white" according to theme support page, https://archetypethemes.co/blogs/impulse/create-variant-image-sets?_pos=1&_sid=70b5be6d3&_ss=r

So I can see the different images per my selection. 

I wanna add option 3 but I don't know how I can make a image set per option 3, bundle type. 

--->>> Option 1 :  color // option 2 :  size // option 3 :  3packs / 5packs/ 10packs

Please help me to solve this problem:) 

Thank you:)
