How to define Portals/other TrueNAS-specific features for app created via yaml import?

For adding portal/icon:

Ability to configure portal links when adding Docker yaml

Problem/Justification There is no way to add portal links when adding apps via YAML file. Impact It would be nice to have portal buttons when apps are configured via YAML file. User Story I like the YAML configuration very much because I deploy and change apps much faster as when using the wizard and I can also group apps with dependencies together. Because of this I would like to migrate all my apps to YAML but I would also like to keep the portal link buttons for each application.
