Form 16 - part b under different tan numbers

Would any one know in case a company changes TAN address to a different state and therefore obtains a new TAN number in the middle of the financial year, leading to filing of salary tds returns under two different TAN for different quarters of the same fiscal year, will the part B of form 16 be a single one or 2 parts, one for each TAN number? If the answer is yes, how will the tax calculation happen in each Part B. Can a unified Part B mentioning both the TANs issued instead?
