Modify the Data loop functionality - Adding Random data selection from multiple Data Sources

We have test cases where we need two or more data sources with random values from both data source , currently this is how Data source/ Datasource loop works in SOAP UI if there are multiple data sources.

DataSource1

Dataource2

Request

DataSourceLoop2 ( Datasource2>Request)

DataSourceLoop1( Datasource1>Dataource2)

Nice to Have : Why dont we have a check box for random data selection in configuration of each data source . When we do this we will be able eliminate the concept of inner/outer Datasourceloops.
