with Orders Exporter can I export only recent orders?

My client's frequently download the list of orders using the Orders Exporter module. This works, but the problem is that it exports every order since the beginning of time. They have requested the ability to export only the orders that have been placed since the last export was performed. Is there any way to edit the module to do that or to only export orders placed in the last day or other set time period?

If that turns out to be too difficult of an edit for me to make, what could I set up that would allow the clients an easy way to do a mass change of all order statuses to delivered so that on the next export they can just use the built in export only non-delivered feature?

Unless the "test" checkbox is checked, it should only export orders since the last export. Are you sure you have an up to date copy of the mod?

I'm using the newest version. I just redownloaded and installed the newest one listed here: http://www.zen-cart.com/downloads.php?do=file&id=560 to be sure.

Hitting the "...all orders full export" link exports every order since the beginning. Where is the "test" checkbox? I can't find any additional settings for this plugin where such a checkbox might be.

OK, I see. I was thinking about this one: http://www.zen-cart.com/downloads.php?do=file&id=406

Try it out and see if it works for you. It marks orders as "exported" to prevent re-exporting (unless the test box is checked, as I mentioned).
