Manually edit Database of Price Editor?

[Rolf Endres]

Hi there,

is it possible to import a CSV file with stock price data into the database that Price 
Editor uses? Specifically, I am trying to build a historical price database of my 
portfolio, and entering the individual datapoints by means of the Price Editor is 
cumbersome..... 

If so, which file would contain the database, and is it editable with a text editor or 
spreadsheet programme?

thanks,
Rolf
