If I were an RI, and a team told me they planned to switch between Part A and Part B, I would have them weight with Part A, and then Part B, and note the weights next to a description of the part.

Then, when they came for subsequent reinspections, I would look for the part, check their weight, and if everything seems in order, note which is the current configuration/date/time, and clear them for competition.

That way, we know which is their last configuration when inspected, and if they show up on the field with the wrong configuration ... it is their problem.
