Is it possible to automatically create additional accounting lines for a provision doubtful debts?

Hi,

In our business we sometimes send billing invoices to a curator.

The accounting lines that are created by this invoice are:

debet: 1234 Account receivable

credit: 2345 Revenues

Our business want to have an additional debet and credit line for this billing invoice:

debet: 2346

credit: 1235

Also when a payment is received we create these lines:

debet: 2347 Bank

credit: 1234 Account receivable

Our business also want to have an additional debet and credit line for this payment:

debet: 1236

credit: 4123

The purpose of it all is to have a balance amount of zero for all the accounts that are starting with the number 1 (so 1234, 1235 and 1236).
