I am not as familiar with Adagio FX, but it seems to me that one would able to construct financial reports to show both with a few formulas.

We use GAAP for financial and cash for tax purposes and I have been considering this very thing since I drop the income statement into excel to move it from GAAP to tax for tax projections.

I would suggest thinking about washing (for example) accounts receivable (subtract current year's and add back prior period's ending balance) through sales to show total cash sales. You would then do the same with prepaids, payables, and any accruals and it may get you what you need.
