Thanks, Christine. That's exactly the kind of situation that Deep Linking launches are designed to handle. That is, you launch into the tool to 'select' the learning material first, then the relevant custom params are automatically saved into the platform. The teacher really doesn't need to know about the underlying params if they pick the content this way. It might be worth asking the person in charge of that integration if they support that. It's been the standard way to achieve this kind of thing in LTI for a good while now, and is also a big reason in why we chose to remove custom params (at least visibly) from the instance-level in 4.3.
