Describe the feature

When generating connected forms using npx ampx generate forms, the resulting forms should include elements for custom types.

Use case

One of my models has a few custom types, for example:

  // Installation table
  Installation: a
    .model({
...
      // The location of the installation
      location: a.customType({
        lat: a.float(),
        lon: a.float(),
      }),

      // Fields required for Victron integration
      victronConfiguration: a.customType({
        installationId: a.string(),
        portalId: a.string(),
      }),

      // Solar PV plane configuration
      planes: a.ref('Plane').array(),

...


  // Solar plane definition
  Plane: a.customType({
    name: a.string(),
    azimuth: a.integer().required(),
    declination: a.integer().required(),
    kwp: a.float().required()
  }),

The connected forms generation is really helpful, except that it does not include form elements for custom types like the ones shown above. It would be really useful if it did. For arrays, what would be particularly handy is the ability to also add/remove elements from the array (see the "planes" element above).
