Request for availableMeasures, availableDimensions to be customizable of QueryBuilder in @cubejs-client/react

Is your feature request related to a problem? Please describe.
As I import more and more schemas, there are more availableMeasures and availableDimensions get populated in, the selection list in QueryBuilder gets very long, it's difficult to find a measure or dimension

Describe the solution you'd like
add new props e.g. availableSchemas to be array type, accepts expected schema, then all these schemas's measures and dimensions, segments will be set with availableSchemas's measures, dimensions and segments

Describe alternatives you've considered
