你好，我使用的版本是spring cloud alibaba 2022.0.0.0

请问怎样在spring cloud stream整合rocketmq中使用多binder配置，不同的producer和consumer连接不同的集群

我尝试使用spring cloud stream中的配置方式，如下所示，发现无法生效，
查看了源码，spring.binders中，只有rocketmq:com.alibaba.cloud.stream.binder.rocketmq.autoconfigurate.RocketMQBinderAutoConfiguration,
在RocketMQBinderConfigurationProperties类中写死了配置@ConfigurationProperties(prefix = "spring.cloud.stream.rocketmq.binder")
所以只能加载一个binder配置，现在是不支持多binder配置吗？如果支持的话请问怎样配置或者需要怎样进行二次开发？

谢谢！

binders:
    rokcetmq1:
      type: rocketmq
      defaultCandidate: false
     ......
    rocketmq2:
      type: rocketmq
      defaultCandidate: false
      .......

bindings:
      test1-in-0:
        destination: test1-topic
        group: test1-consumer-group
        content-type: application/json
        binder: rokcetmq1  #这里报错
      test2-out-0:
         destination: test2-topic
         group: test2-producer-group
         content-type: application/json
         binder: rokcetmq2 #这里报错
