I have a custom relationship between two lists. To maintain parity between lists, I prefer to rollup certain custom fields from one list to the other instead of adding the same custom field (with potentially different input) to both locations. I'm also beta testing custom fields by task type, if that matters.
Right now, when I open the Related section of a task in either list, there's both a default Related tab listing all items related to that task (in my case, grouped by custom task type), including custom relationship tasks, and a separate tab just for custom relationship tasks. This layout is mentioned in the Help Center: https://help.clickup.com/hc/en-us/articles/29728065999383-Relationships-on-tasks
I can configure the separate custom relationship tab to display rollup custom fields as columns, but I cannot configure the default Related tab to do the same. I would like to see (and interact with, in the case of clickable URL type fields) those rollup custom fields in the Related tab to spare myself an extra click to the other tab.
