This is on the right track but it is flawed currently.

With dynamic datasources there can be multiple instances from the same template, the only differences being the start block and arguments. So there needs to be more information passed through to remove the correct datasource.

I think the best solution for this is to provide the ability to list dynamic datasources for a template. Then the user can select the appropriate one to remove by providing the index.
