Since making the table additive will change some cell values, it is not obvious how the sensitivity rule is influenced: only the cell values is adjusted, not the underlying contributions. That's the reason why the statusses are not maintained when making a table additive.
However, I assume that the tabular input has the statusses you want. Then a workaround would be to put these statusses in a "apriori file" (.hst) and import them after the table is made additive.
