Flat sum of tax per unit instead of rate

Hello all,

I was wondering whether there would be anyway to set tax as a lump sum per container then as a % rate. For example, when manufacturing beer, there is an environmental tax of 8.93 cents per container which is not a % of price. I could get 8.93 by applying whatever percentage of the price would equal 8.93 for each item but with prices changing really fast it could mess up the system if an untrained user is using it.

Thank you for whatever help you can send my way,
Lee
