How to use template for selector fields

Configuration
1

it doesn’t work

description: ""
fields:
  field:
    selector:
      select:
        options:  "{{ state_attr('select.someentity', 'options') }}"
    required: false

error: Message malformed: expected a list for dictionary value @ data['fields']['field']['selector']['options']

Attribute has value:

[
  "sweeping",
  "mopping",
  "sweeping_and_mopping"
]

I don’t think any of the selector options support templates.

I hit this issue the other day (different option) and opened a feature request.
