Yes, in fact if we could organize fields ourselves it would be fantastic. When we add a "new" custom field it is just added at the end. Being able to add a field to a pre-existing grouping or to place in alpha order would allow for more efficient use. Because we have added info to some of the fields, we cannot delete and rearrange (we'd lose the already added content!).
