It;s been suggested that this be driven by the lead schedules to calculate the income, expenditure, assets and surplus automatically for tests 1-4 under "consider these major areas" with the user manually typing in materiality in the "overall materiality level to be adopted" 

Again this is something we will look at - we agree this would be helpful but requires a new feature to be added to the code which we will have to think through as we like to make keep the software very much a cohesive unit where everything we add contributes to the whole rather than just 'hacking' on features. We do want to add the ability to create a 'dummy' set of accounts from the trial balance, perhaps eventually a full report writer to produce complete financial statements, so I think it would make sense to tie this in to that feature as it will involve calculating total expenses, assets etc.
