I am delighted to tweak calculators to suit your local needs, just let me know and I'll quickly let you know if it is possible. I am willing to build and publish new calculators as well, charges commensurate with the amount of work required. Please send me feedback on what is good and what is not. Thanks! -Dr.K.
