Idea: Import-DbaCsv - option to include filename in new field

[match-gabeflores]

I often have to load a group of csv files (sometimes 20+) into one single table. Example loading monthly CSV files into one destination table. Import-DbaCsv works great for this. Not sure if this is possible, but it would be convenient if it could also include an additional field with the filename (either filename or the full path) in the table. This would be a separate optional parameter.

example: if loading two files (with just field field1), example table schema would look like this.

field1	filename
value1	a.csv
value2	a.csv
xyzvalue	b.csv
abcvalue	b.csv
