Reservation System Flaw

I have noticed someone (I presume one user)has made 30m reservations between 1:00 and 4:00 with only 2×5 minute exposures Ha in at the first one, then 4×5 minutes SII in the second 30min reservation. These captures are on the same target, NGC2070!! The system should pick up on the discrepancy between the total exposure times and the booking period. With Stellardock currently everyone can see what is happening. Will there be a limit on the number of sessions on one Telescope per night when the system exits beta which would prevent this type of waste? It should !
