Where do we validate conditions of 'Suitability' in Plant Maintenance??

We define 'Suitability' in plant maintenance task list data. It is used to define some conditions which are important to perform some specific operation. Suppose we define in the configuration that for plant 1000, to perform a welding, welding certificate is required. A Suitability with suitability key '10' is defined.

Now, I have to perform a maintenance operation i.e. welding, and want to apply the suitability. I can't find any option in the Task List to enter the suitability, then how to validate that to perform that operation, a person with welding certificate will do the operation??

Please suggest.

Thank You.
