I got your point and requirements will always come up with strange logic. What I intend to say that you got to understand the influence of third party audit over the design you build. Questions will be asked.
Over in a long run, periodic audit will find discrepancies in the system and users will keep on updating the audit finding with different justification.
If I were into your place, I would have adopted the system where all MICs be valuated as rejected (Wherever defect recording is required) and others accepted (only when no defect is there).
Considering user concept of accepted or rejected inspection (irrespective of the MIC valuation), I'll emphasis on valuating the Usage decision accordingly. If inspection is accepted, give the Accepted UD otherwise Rejected valuation should be given.
As far as you requirement to contain more than one result against a single MIC (Correct me if my understanding is not right), change the control indicators of MICs from Summarized recording to Single recording. You might need to modify the sampling procedure also if sample size is one (1). This will allow you to explain the MICs field and multiple entries can be entered, all against a single MIC.
