Feature-- Add stage details for incident report


I tried to create an incident report. I cloned the standard report on incident item, but just want to add the stage details like time, comments, attachment names.
As far as I can see we can only choose the section “security incident stage” for a table, but there I only can add the name of the incident stage but no further details
I created a filter, but for filters only the section “security incident” is available but not the “stages”-section.

Table object for section “stage” - can’t select comments / attachments as fields:

Filter object, only section “incident” is available, no section “stage” thus my filter with comments / attachmest cannot be selected:
