Allow to copy the pom dependencies only of the selected extensions

Description
Consider this scenario: I'd like to create a REST endpoint which accepts Movie JSON object which this endpoint then will publish to the Kafka channel and have a Kafka consumer accepting Movie.
So I go to code.quarkus.io, select Resteasy Reactive Jackson, and Smallrye Reactive Messaging Kafka, and Generate Application (using one of the Generate Application options - ex, download it as zip), and then setup my workspace, and do mvn quarkus:dev and implement the application.

Next, during the demo, I'd like to show how the Kafka consumer can have Movie object saved to DB.

The only option right now is to go to POM of the application downloaded from code.quarkus.io and manually add for ex hibernate-panache-reactive and reactive-pg-client dependencies, but it would be great if I could return to code.quarkus.io, select hibernate-panache-reactive and reactive-pg-client extensions and have an option just to copy, in this example, the following fragment:

<dependency>
      <groupId>io.quarkus</groupId>
      <artifactId>quarkus-hibernate-reactive-panache</artifactId>
 </dependency>
 <dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-reactive-pg-client</artifactId>
 </dependency>

This way I can copy and paste it into my application pom instead of having to manually type these dependencies.
