It seems I need an actual splitter and partial shipment plugin for my needs.I’ve since deleted this plugin. Hopefully they can improve the features in future, ![](https://secure.gravatar.com/avatar/7a1229fb9a6fd02b9e86ac866c0fba5c86b58e4491b1799e92434a153c2a14fa? s=60&d=retro&r=g) ### 󠀁[Great plugin](https://wordpress.org/support/topic/great-plugin-21656/)󠁿 [](https://profiles.wordpress.org/katoen/) April 26, 2019 Hi, exactly what i was looking for.
