Yes, please!! This is also SO helpful when training new cataloging staff. It's difficult to always know which field needs updating since sometimes several require formatting.

Would love this feature! Since formats/TOMs are currently hierarchical and may have multiple ways to create them (eg in the 006, the 007, the LDR, the 008 or a combo of all of these), it's not always easy to tell if you made the correct change, or made all the changes you need to get the format you want. It would be much easier to tell if the fix is working if you could see the change in format right in the bib, rather than opening a duplicate check or going back to refreshed search results.
