Its possible to submit a manual order for any security in your universe during live trading however doing so won't add that security to your active insights if you're using the framework models.  Unless you specifically code for the occurence your weighting might be thrown off.  It would be awesome if we had the options to manually fill out the fields for a new insight as an addtional way to fill out a manual order that way the framework process would treat it as if the trade was emitted by a specific alpha model.  Assinging a specific name to this manual freature would help quite a bit as well although its probably not necessary.  It would just make handling manual orders easier from the portfolio construction in some cases.
