What if subjects can titrate some kits and not titrate others?

It's not a problem at all. The workflow is exactly what you expect.

1. Define all the kits as you do normally, including:
   • The kits that subjects need to titrate, such as the investigational product.
   • The kits that subjects don't need to titrate, such as a box of syringes or a rescue inhaler.
2. Define the kit type titrations.

   When you create the kit type titrations, make sure you include only one kit type, the one that you're titrating. Don't include the kit types that you're dispensing separately.

3. Define the dispensation schedule by associating every kit type with the appropriate visits.
4. Associate the kit type titrations with the appropriate visits.
