We currently import our orders using a CSV to Shipstation from our internal database. 95% of our orders are standard "kit" configurations consisting of two boxes with the same dimensions and weights each time. We always ship these orders via Fedex.
It would be very helpful to be able to configure the order using two boxes in bulk for these orders. Upon researching this capability, it appears that it is possible to configure and apply a preset in bulk, but the preset only allows one box (not multiple ones). There is a package set feature that allows multiple boxes to be configured, but a package set cannot be applied in bulk to multiple orders.
