Tax authorities may or may not prefer paper-based environments. My experience is that they have no preferences, so long as you can adequately justify your claimed income and expenses. Which accounts you post transactions to are generally internal preferences, not requirements of tax authorities. In those cases where accounting structures are mandated for corporate entities, Manager may not be an appropriate accounting choice anyway, due to the required complexity of record-keeping. Yet even then, the ledgers of the accounts will be the necessary proof, not the indication of an account on an individual printed voucher.
I offer just one more observation. No one else is asking for this capability that I know of. No one reports that their tax authorities demand paper records or that those records must show account allocations. This causes me to conclude you are asking for program modifications specific only to your specific practices for double-checking others’ work performance.
