Holidays (Ship date) Opt-out Option

As I know, Shipstation automatically pushes the ship date on a national holiday, however, I am wondering if we can manage it. For example, yesterday was Martin Luther King Jr (01/20). Day, but our company had regular hours and so did FedEx. All the labels we created yesterday had a ship date as of today (01/21), is there a way to manually opt out of some holidays instead of changing the ship date when creating the batches every time?

I am aware that we can manually change the ship date before processing every batch.
