I want to create a nested entity, an entity that is a combination of a look up entity and a number. In markdown format. My current training file looks something like the following:
# intent: select_galaxy
- select [milky way](galaxy)
- select [milky way 11](star)
- set [bright](threshold_type) [10.4](number)
- select [ [milky way](galaxy) (number) ](star)
Any ideas how to achieve that?
