At the moment, no, that's not supported, but it's certainly something I can look into supporting in the future for users that need it. In the meantime, you can use the "Rearrange pages" feature to duplicate your pages, then crop each instance of a page to have one of the halves. To access this, you can either long press a piece on the library screen, tap "Edit Piece" at the top of the screen, go to the Files tab and tap the Page Order field, or with the piece loaded, tap the center of the screen to bring up the overlay, tap the second icon at the bottom left and then tap "Rearrange pages".
