Batch-action for 2 images in a set

Hi, I created a nice action which helps me to work on 2 (currently loaded) images in combination. Now I would need support on how to apply this existing and successful action in a AUTOMATE/BATCH process on a folder full of files. So instead of just loading 1 (one) picture at a time and applying the action within a standard batch to a single picture -  I would need that photoshop loads 2 (TWO) images from my source folder at the same time - applies the action-batch - and then continues to load the next 2 pictures, then the next 2 etc....  

Thanks looooads for your hints! Gerald
