Link one post to another

It would be good to have options to link one post to another in Featurebase, as now I have two post that are related and connected but can't put like "relationship" and link them together as part of one feature.
I can put link but that's not good solution for me. I would like to see main post and connected post to that one. Something similar as "Task > Subtask" or even Relationship to Taks as Clickup has, but visible not hidden.
