Yes, exactly that.

There are two options that could be used for that:

1. `--strip-components', that removes the specified number of directory
components from a file name (this option works when extracting from
archive), and

2. `--transform' option that alters file names according to a sed-like
expression (this option can be used both when creating and when
extracting). E.g. the command

  tar -cf archive.tar --transform 's,.*/,,'

removes all directory components from file names before storing them
into the archive.

It depends a great deal on where you plan to extract your archive.
