At the current time, Adagio Invoices does not support multi-selection of invoices in History when there are more than 10,000 records in the file. There were technical reasons for this limitation, and it's possible that our new database interface used in Adagio 6.8 will be able to address this, though it is untested.

The ability to multi-select is certainly something on our suggestion list for Adagio Invoices. I cannot promise if and how soon this could be implemented.
