Yes, bundles, passes and memberships can all be set to only be usable by the account holder. If you check the control to prevent use with sub-profiles in the package settings then the package will show as invalid for any booking that involves a sub-profile, even if the multi-book control is enabled.
To implement this setting, follow these steps:
Navigate to Packages.
Select the relevant package.
Click Edit this package.
Tick the checkbox next to Prevent use with sub-profiles.
Click Update package.
This setting is particularly important when customers book sessions for themselves and sub-profiles (e.g., their children) using a shared package. Enabling this option ensures that the package is restricted to the main account holder, preventing unintended sharing.
Changing this setting on a package will affect both existing live instances and future purchased instances.
