Be able to alias the "SOURCE_TABLE" column in a multi-table input component

If combining multiple tables using a multi-table insert component and those tables have the column “SOURCE_TABLE” within them, if you select “add source table” as an option, the result of the component columns will be “SOURCE_TABLE” twice, among the the source columns.

It is not possible to reference this additional column in later components. In a calculator, it uses the first column “SOURCE_TABLE” which comes from the tables. It ignores the values from the component. Other components downstream may generate an error.

The current workaround is to engineer the sources to use an alternative column name but this may not always be possible meaning we then can’t use SOURCE_TABLE within the component.

Request.

Add the ability to optionally name the SOURCE_TABLE column that is generated by the multi-table-input component.

Optionally, add a rename element to the table input allowing developer to rename the columns of the merged tables before output of the component.
