Let’s say:
- I am on instance A.
 - I browse on a community that is on instance B
 - a user from instance C post something on that community B.
 
Now i want to share a link to this post. Which instance should i pick?
- A my home instance
 - B the community
 - C the post author
 


At this moment the web interface doesn’t support this.
I use the app Voyager on my smartphone. I can set in the settings that the share link target links to A, B, C by default or that the app asks me everytime.
