Hide bundled products for specific bundle

I really enjoy your plug-in. There is just one thing I can’t accomplish. I’m selling 2 types of bundles.

1. A bundle where the customer should know what is included in the bundle, so the customer can take the bundled products into account when adding additional simple products.

2. A ‘surprise’ bundle where the customer wants to be surprised. Currently I have marked these bundles as simple product. This might work well for the customer, but this is quite time consuming for me. I have to adjust the stock manually and create the stock picking list manually as well.

I’m wondering if it is possible to hide the bundled products for the customer in case of a ‘surprise’ bundle while the bundled products remain visible in the back-end.
