How do I view a post made on one instance from my instance?

I’m on kbin.cafe. Let’s use the top post of kbinMeta as an example.

When I access this same post from kbin.cafe, the link is instead

https://www.kbin.cafe /m/[email protected]/t/2219/PSA-Upvote-is-not-an-upvote-like-you-are-used

So I can’t just change the kbin.social link to kbin.cafe and append an @kbin.social to the magazine name. I have to search for the post on kbin.cafe, which often won’t succeed if the magazine the post is on didn’t start federating over until after the post was made. I care about this because I would like to be able to interact with posts with my current account.

I can always just have a sock puppet account on kbin.social that I follow with my kbin.cafe account, and use the sock puppet to boost the post so I can access it on kbin.cafe. For me this is actually realistic option given that I made a kbin.social before I found out about kbin.cafe. But it feels dirty, and I would like to not have to constantly switch accounts to access one post or interact with it.
