More than 2 cloud-init keys for instance data

Hello! Is there a way to use more that 2 (user and vendor) cloud-init keys for instance-data? To use them in some base profiles and apply each on top of others. In the cloud-init docs I see the mention about that when keys was user.* there were user.any-keys, and real any user.* passing LXD config validation and persists in profile, but not works.


Please can you give an example of what you’re trying to achieve?
