Hi @ab_cdef,
While you could use an external lookup (or typeahead) to (1) find and connect one request another, and it then might be possible to (3) fish out enough information in a calculated parameter to then create a clickable link, although an external lookup might be able to also show you the status of the target (where I believe a typeahead cannot), that status would be "as of the moment of connection" (i.e. as you are making that connection), but -- being static and decoupled -- would become stale, and not show you the target's status as it changes. So...not recommended.
Instead, if you have Fusion, you could poll/pull the data to keep it fresher.
Alternatively, if you simply tagged such related Requests with some custom data (e.g. a Job Number, the date, etc.) in a custom data parameter, you could then create an Issue report that would filter (and/or prompt) for such related Requests, group them by that custom data parameter, and use the resulting (always live) data to compare their status values "beside each other" and then take appropriate action.
Regards,
Doug
