Match bank-account-activities from unknown users after 3 months to general account

[marcelb98]

If a user transferred money to us but did not provide a valid purpose for the transaction, the bank-account-activity is not matched automatically to the users account.
Furthermore, not all users are noticing this which results in a considerable amount of unmatched bank-account-activities.
As we want to have a clean accountancy, we want to account all bank-account-activities to an account.

I suggest that we automatically account bank-account-activities which could not be matched to a user (automatically or by our support) withing 3 months to a general account ”Beiträge, Mitglied nicht zuordenbar”.
This way we also get an overview about the amount of money which was transferred to us from not known members.
