We use the last 4 digits of a phone number.
This makes it very easy for the primary guest to remember.
Recently the guest last four digits of their phone number matched our cleaners last four digits of their phone number.
The lock automation deleted the guest and the cleaners number at once.
It would be great if we could have a list of numbers in OwnerRez that would be "off-limits" for lock code generation and then it would default to a random number if the guest last four digits are blacklisted.
