It sounds like the problem they have is that they want you to be able to
make changes, but perhaps not make them active until they are all
finished. Is that what the problem is?
This can be solved in a number of ways. You can mark records as
"testing", and then have an approval step which copies the testing records
over the production records. You can also have an "active date" on your
records, and then mark your records as being active in the future.
I think we need more information on the "whys" of this before making
clearer suggestions.
