Hi
The module does not support the group options as there is no code written for this to fine user based on group on dating.
Its something need to built a new module that has a new layout written for this. Its not easy i can suggest you changes as it need a dedicated developer to built a module.
If you are a developer you can find module file in /module/js_dating and customize it, or hire a developer for this task.
Sorry for not being much help in this case as its something beyond support scope.
Regards
