Multi Order for WooCommerce

It works perfectly well.

I use this plugin to split parcels toward multiple carriers when the order of the customer requires to split his order in several orders / parcels.

I use it in the plugin https://wordpress.org/plugins/colissimo-delivery-integration with the filter "alg_mowc_exclude_cloned_order_postmetas" which allows not to duplicate the post_metas of my own applications. Total satisfaction.

It would be interesting to also have a filter to choose the quantities of each of the items to be distributed in each suborders (in other words, a filter that would drive the number of suborders to create, and the distribution of items in each). Instead of a filter it could also be a selection panel when clicking on the "Create Suborders" button.
