I agree with Marshall’s comments since I utilized a similar logic myself with no auditory complaints.
If you wish to formally justify your approach, this can be done within the documented Quality Procedure for “Control of Documentation”. One method involves defining your Quality system by an Issue Number and Revision number logic plus combining concepts such as those below -
The issue number is simply a one number figure pointing to the level that the quality system is at, starting from number 0 (Zero) which indicates that the overall system is draft. When the issue number is increased to 1 (one) that means that the system is at the first official and final status. When major changes on the system take place, like most of the quality manual most of the quality procedures and work instructions have been amended 6 times, the issue number may be increased.
