I have a very similar function is only one previous report and the other future, how can I optimize and write beautiful?

public bool AnyPreviousReportByGroup(int groupID)
        {
            if(this.GroupID == groupID)
            {
                return true;
            }
            else
            {
                return PreviousReport.AnyPreviousReportByGroup(groupID);
            }
        }

        public bool AnyNextReportByGroup(int groupID)
        {

            if (this.GroupID == groupID)
            {
                return true;
            }
            else
            {
                return NextReport.AnyNextReportByGroup(groupID);
            }
        }
