Check Cherry has an availability section that can help you manage your equipment, including double-sided backdrops. Go to Manage --> Business Settings --> Availability --> Availability Rules.
To set up availability for a double-sided backdrop:
Click Add New Rule.
In the Backdrops section of the rule, select the 2 backdrops that make up the double-sided backdrop.
Click Save to create the rule.
An availability rule links two or more products so that when one is booked, the other is also considered booked, and is made unavailable.
What if I have more than 1 copy of one backdrop that I use in a double-sided backdrop?
Each side of a double-sided backdrop needs to be entered into Manage --> Backdrops as a separate item; then you will create an Availability Rule to link them together.
If you have multiple copies of one backdrop, and use one or more of those copies in other double-sided backdrops, you will need to create multiple copies of the side that you use more than once so that they can each be assigned to a different double-sided backdrop.
Example: You have 2 double-sided backdrops - a red/white and a blue/white, and each has it's own white, so you have 1 red, 1 blue and 2 white. You will need to set up 2 white backdrops and differentiate them (ex: white 1, white 2). Then create an Availability Rule, assign White 1 with red and save it as Red/White. Create a different rule and assign White 2 with blue and save it as Blue/White. The rule will now allow a White/Red backdrop to be booked at the same time as a White/Blue backdrop.
