Edit schema with precision for Decimal types in parquet files.

I have a parquet file from which amongst all the columns of data, I have one shown as BigDecimal, which is a format that is not included in AWS. I would like to format it as decimal(38,18), but it seems like I can't do that using Glue, right?

Do I necessarily have to build a new table specifying that column with that format?

I'd be glad to know in order to not build a new table just for it.

thanks in advance for any insight you can provide.
