将两个标签合并为一个Grafana变量

我想根据这些数据生成一个包含唯一值

application\u name-result

的grafana变量：

{app="abc-api", application_name="abc-processor", application_type="processor", stream_name="test-stream", result="success"}
{app="abc-api", application_name="abc-processor", application_type="processor", stream_name="test-stream", result="failure"}
{app="abc-api", application_name="abc-processor", application_type="processor", stream_name="test-stream", result="duplicate"}

{app="xyz-api", application_name="xyz-processor", application_type="processor", stream_name="test-stream", result="duplicate"}
{app="xyz-api", application_name="xyz-processor", application_type="processor", stream_name="test-stream", result="success"}
{app="xyz-api", application_name="xyz-processor", application_type="processor", stream_name="test-stream", result="failure"}

我可以单独创建这些，但无法将其组合在一起，例如：

stream_name :: label_values(stream_name)    
application_name :: label_values({stream_name="$stream_name"},application_name)
results :: label_values(document_index_total{stream_name="$stream_name",application_name=~"$application_name"},result)

请给我指路

我希望变量输出为：

abc-processor-success
abc-processor-failure
abc-processor-duplicate

xyz-processor-success
xyz-processor-failure
xyz-processor-duplicate
