If it was aimed at me, then NO, you cannot: it is one of the most terrible piece of software I come across - I stick to my beloved LDD + with the ability of adding ANY NEW BRICK I WANT there is absolutely no need to try to use and learn that sh*t, sorry (and I actually did before only to run back to LDD ASAP).
Really, if author do not want to update his older software, he could release his source files so some experienced Java programmer could continue as Blueprint has too many mishaps or purely done stuff there (I even don't know where to start, gee).
