Its difficult to select models from different folders from Explorer or Designer module, so there is no straight way. You will have to do a search (Find) on the parent folder for all models, then only you can select multiple models.
An alternative way is to create a group for the models to be evaluated and in the group create shortcuts to the models you are interested. Once the models are evaluated witht he semantic check(s) the shortcuts can be deleted and replaced with new ones if you want to.
