Right as Vladx noted. The doc is from an older CCS version but should still help. Let me know if it does not and i will put some screens together and share. The idea is the following
1) Download and install Crystal Reports (free) and launch it from Visual studio
https://go.sap.com/cmp/ft/crm-xm15-dwn-an009/index.html
Submit form and you can download it. This then is usable from Visual studio.
Under visual studio…create new windows form application…Add new Item->Reports->Crystal Reports and then Open the RPT file that you exported from the base template from CCS
2) Copy/Paste the base Reporting template from CCS. Export the copied template to a RPT file that you can open in Crystal Reports.
3) Edit using Crystal Reports
