[rules-users] entry-point and accumulate in a guided rule (BRL)

See screenshot, I want to combine an entry-point and an accumulate function such as (the below is DRL, which works) *rule "GSS-Sev1-Monitor"* * no-loop true* * dialect "mvel"* * when* * $ticketStatistics : TicketStatistics( $ID : ID == null )* * accumulate($supportTicket:SupportTicket( ticketStatisticsID == $ID , severity == "Sev-1" ) over window:time (5m) from entry-point "gss-support-stream", $num : count( $supportTicket ))* * then* * $ticketStatistics.currentTicketCount = $num;* * update( $ticketStatistics );* * end* I can't seem to re-create this in Guvnor (BRL)
