When we assign a torch rental, it gives it for each day the client is reserving. So if they are doign 5 days diving, they get the torch $15 × 5 days.
Torches are typcially only rented for a night dive (not always but like 99% of the time its only for night dives). So for this client doing 5 days diving plus a night dive the torch rental is showing as $15 × 5 when it should be only $15 × 1 (one day of night diving).
So we need a way to adjust the torch rental by number of days - not each excursion reserved.
Same would be for the camera rentals. In most cases a GoPro gets rented one day, not every day.
