Those are fair points, but a lot of things you are suggesting are already possible.
You can insert a report into a plot (in Capture 2024), merge a report from other documents, or create a template Capture file with already-made reports.
You can also adjust how certain items are named if you make use of Report items.
If you need an item that does not exist in the library, rather than using a placeholder fixture, why not ask the library department to create that fixture for you because the turnaround time for that is really fast (a couple of days maximum)
