Allow SSG to be created where a ticker is not included in the data feed or from manual data
I am researching an ADR of a company, which trades OTC. (ex: DKILY, Daikin Industries, a $53B market cap company) I am unable to start an SSG in this company, as the ticker is not found in the data.
I think there should be a "manual mode" for the SSG, which would be useful not only for OTC companies, but also companies listed on foreign exchanges. It could also be useful as a learning tool, to find and populate the data, in order to become familiar with their meaning and source.
