Optionally prevent Lightroom from updating curent view in smart collection/filter

I use Smart Collections and Library Filters a lot to fix isseus in my photo library. Like adding keywords to photos not yet keyworded or adding location fields. However, because Lightroom today updates a collection/filter in real time it means that if I have a filter on photos without keywords they are immedeately removed from the view as soon as I enter one keyword, and I do not get a chance to add another. So I would love to have an option to NOT automatically refresh the current view even if the criteria for the view changes.
