Woocommerce Order Status Change depending on meta (input)

Hi there

We have been trying to figure out how to change the order status depending on it's meta information. On our website we have two order options a "standing-order" and a "quick-order" these are radio buttons created using the tm product options plugin. At the moment all orders default to a custom "quick-order" status. We would like all orders with the input selection as "standing-order" to be given the "standing-order" status we have created.

Unfortunately this also creates a issue when the user wants both a standing order and quick order. Having all products processed as separate orders would be ideal as they could retain their own status (order both standing and quick order within one basket). But disabling the option of adding both a standing order and quick order to the basket at the same time would also work for us.

Thanks
