Add column to a table column (from Source)

Hi,

Is it possible to add the sheet "Name" into the "Data" column as a custom column?

I wanted to do this because:

1. the sheet name is a distinguisher among the tables

2. the number of columns within 1 table varies (so I would do a Table.Combine formula after)

I'd really just want to insert that sheet name into the table before the Table.Combine function. 

Thanks!
