Can we change the file format for exporting Reconciled Cash Management items?

We have updated the general file format for exporting search results (for such as journal lines and unreconciled items) but this does not appear to have been picked up when exporting the reconciled items from the Manual reconciliation screen.

Is it possible to update this file format so it is not the old .xls format - so update to such as .csv or .xlsx?

We have updated the format in "Manage Applications Core Administrator Profile Values" > File Format - and this has worked for what appears to be all other exports.
