Extra icons question
 

I drafted up four icons in Inkscape and I want to use them for Phone, Conversations, Media Player, and Photos. I don't want to change the current ones, I like the faenza icon pack. I just want to add desktop shortcuts that use these four images.

I know there's a way, and I use to know it. But searching around hasn't jogged my memory and I can't seem to think it off the top of my head.

If anyone's got a solution, great. If not, thanks for checkin out the post.
