[galaxy-user] Move data between histories?

Hi, I was wondering if there was a way to easily use (or move) data between different histories. I have a large fasta file that I'd like to use in a work flow, but this fasta file only shows up when I have the original history open. Is there a way to select data files that exist in different histories or do I have to download the file and re-up it to any new histories that I'd like to use it in? Thanks in advance for any help.
