How can I find if the customer statement for a customer for a period has been printed ?

How can I find if the customer statement for a customer for a period has been printed ?

I researched a bit with no luck.Like on invoices i could lookup the table ex - ra_customer_trx_all for fields : print_original_date, print_last_printed, printing_count , print_pending

Is there some table for Statements that would indicate that the statement has been printed for a particular customer and period ?

ar_statement_headers and ar_statement_line_clusters had no Data in then as I believe they are interim tables and get flushed out when the statement generation is complete.
