Crystal Reports vb.net crystal report group selection help

Message

I have a listbox, a crystal report and crystal report viewer in my vb.net winform application project

My crystal report has ID, Status, and Address fields (details and page header)
The crystal report is grouped by a field called Project Name, and for example, it would look something like:

Report Title
      ID                    Status            Address
101- Project A (Group Header)
365357                 Done              City Street 1
537385                 In Progress     City Street 3
102- Project B (Group Header)
356553                Done              City Street 33

753567                 In Progress     City Street 55
102- Project C (Group Header)

653766                 Done              City Street 54

467464                 In Progress     City Street 67

So the project is grouped by the ProjectName field as shown above. 
The case is, I can add or remove ProjectName as items in my listbox as a user

So, for example, at some moment, my listbox can have the items:

101- Project A

102- Project B

102- Project C

and if I remove the first and last item using a button, my listbox would have:

102- Project B

 The question is, how do I use group selection in vb.net crystal report to filter and show ONLY the groups and their fields which are also there in the listbox?

So, the user can add or remove items from the listbox at runtime, and vb.net would dynamically add or remove those particular 'projectName' groups from the report

How to do this? Using group selection? Using subreports? Some formula or parameter field? crystal syntax? Please advise

Thanks
