It is possible at the moment, to get security setup's from a file, if it conforms to these standards:
1) It must be a comma separated file.
2) In the first column there must be a name (name of the security).
3) In the secon column there must be an import id code (Yahoo code).
4) For the other fields, you can enter values yourself, eg. currency, etc.
This way you can cut and paste eg. company information from the Yahoo finance website, edit it in the notepad editor, so that it follows the rules above, save the result to a file, and then import the security definitions here.
The functionality will be improved in comming releases of the program.
