Filter Pre-ordered orders

Hi,
I recently downloaded the VillaTheme Preorder plugin for Woocommerce, awesome app, very useful !
I noticed there is a “Pre Order” column in the Order Admin Page, but i can’t filter or sort through this column. Is there a way to filter only the pre-order orders ?
(I noticed that I can filter only pre orders products in the product admin page, but it’s not what i’m looking for)

Thanks in advance,
Greg
