Us Payoll : Tax Model Changes : Creation Of A New Tax Class : Impact

Question

Hi Experts,
Has anyone earlier created a new tax class specification of PC 71 for a wagetype so that it is taxed only for a particular tax authority , if yes how did you handle the impact on the other tax authorities ,did you create new entries ( with the new specification ) for other tax authorities as well so that the existing tax calculations happen as it is.
The issue is explained IN DETAIL below :
We have one requirement to include certain wage types X Y Z for  the calculation of Transit  District Excise Tax /435 in the tax authority ABC
When we checked our system, for these wage types X Y Z the corresponding tax classification is set as 0 ( Regular taxable wages ) which is linked to tax type 1 and not linked to 35 tax type , so we need to assign it to a specification which is having both 1 and 35 tax types. We can assign this to 935 which is linked to both 1 and 35 however this will impact all the wage types that are linked to 0 ( Regular taxable wages ) specification in PC 71.
Our business does not want these other wagetypes to be impacted i.e the requirement is that ONLY X Y Z wagetypes should be included in the calculation of Transit District Exercise Tax /435 for the tax authority ABC.So the option is that  we have is to create a new 71 tax class specificaiton say * and assign it to these wagetypes and then create a new entry assining this * in the table  T5UTM to 935 for this tax authority so that it is taxed for Transit  District Excise Tax /435.
However since we are assigning a new tax class specffication to these wagetypes, there will be a impact on ALL THE OTHER tax authorities where these wagetypes X Y Z  are having an old specification of  0 ( Regular taxable wages ). So we have to create newe entries with this new specification * in the table T5UTM so that the current tax calcutions are not impacted.
We have about 500 tax authoties or  500 tax models where we will have to create new entries with the new tax class specirication '" * " , so that these wagetypes are taxed as they are being taxed today, for all of the other tax authorities.
Has anyone earlier created a new tax class specirication of PC 71 , if yes how did you handle the impact on the other tax authorities ,did you create new entries for other tax authorities., which is next to being impossible as we cannot create 500 entries.
Alternatively we are looking at using the TAX MODIFIER for this requirement , please advise if anyone has used TAX MODIFIER  for this kind of a requirement mentioned above. Any suggestions are most welcome.

Yes we are also referring to the same and this is the actual issue we have , each tax authority has its own tax model. We have to customize (add) this new tax type in the tax models or it won't be considered ( as you have mentioned ).
But we have over 500 different tax models and we cannot be adding this new specification in each tax model , Please advise how this could be handled other than writing a rule. We are just thinking loud if there is anything that we are missing.
These wagetypes are quiet common in all tax authorities , so have to be added in all the tax models i.e. for all tax authorities.
