Skip columns while copying data into redshift from S3 using copy command

Question

I have a CSV table in S3 with 100's of attributes/features, I don't want to create table in RedShift with all these attributes before importing data. Is there anyway to select only the columns I need while copying data from S3 into Redshift?

There are couple of options listed in aws forum for this problem, take a look at https://forums.aws.amazon.com/message.jspa?messageID=432590 if they may work for you.
