I have the following query in M:

```
= Table.Combine({
Table.Distinct(Table.SelectColumns(Tab1,{"item"})),
Table.Distinct(Table.SelectColumns(Tab2,{"Column1"}))
})

```

Is it possible to get it working without prior changing column names?

I want to get something similar to SQL syntax:

```
select item    from Tab1 union all
select Column1 from Tab2

```
