Custom keys on questions in rancher-compose.yml

is there any way of putting meta-data / custom data into the questions in rancher-compose.yml ? I have added foobar: true , and whilst I see “foobar” in the rancher-compose.yml section in the catalog api call, the questions do not have the foobar key

Are you looking for something like this?
