Not possible.

研究方向
Examine the current md selection list component implementation in the Angular Material repository, specifically how single selection and multiple selection are handled. Look at the selection model and keyboard events. The feature requires adding shift click support to select a range of items. Consider existing patterns in other Angular Material components like cdk list. The implementation should integrate with Angular Forms and maintain accessibility. Review the issue comments for any additional user expectations.
