Yes! We keep a list of all SOP's with revision numbers and effective dates (like a table of content) that way when we do a review it shows which revision was reviewed.
And we do revise SOPs quite often.
Also, with some of our manuals (We supply ingredients to may different industries: veterinary, food and supplements and to global industries, some of our customers require specific documentation/manuals) we will write the manual using the SOP name and number, but with the statement of Current Revision of. That way we do not have to re-do the manual every time we make a change in our SOP. (Of course we make sure in the SOP revision review process that the change does not effect the manuals purpose).
