.Net 4 Workflow switch activity, how to provide possible values for the cases?

We have rehosted the Workflow (4) designer in our application. This application has a database where certain values are stored. In the rehosted designer I added the Switch activity and set the type to one of the custom objects that are stored in our database.

Is it pos开发者_运维技巧sible to somehow provide a list of possible values to the add case value dropdown of the designer?

The answer is NO The best thing I've managed to achieve with this issue is to implement custom Constraint for Switch< YouCustomType > activity that invalidates the Activity if unknown case was used.
