renaming of securities. To be able to change the name of securities based on symbol. Some sevice providers do not provide the name of the security, they only give the symbol in their eod file. If one has a file which contains the name as well as the symbol, The Downloader should be provided with a facility to overwrite the previous name or create name. For example, name of all securities is in lower case, and I have a file which contains names in upper case and symbols with new names of securities, the downloader should overwrite the previous names with new name. Right now renaming has to be done manually which is tedious.
