Creating and editing Postfix completion templates.

Is the ability to add, remove, and/or edit postfix completion templates in Intellij 14?

Searching for this answer has been rather difficult so I assume we cannot.
I simply wish to make a .souw to expand a string, etc to a output.println("blah blah"); much like how str.sout would translate to System.out.println("blah blah");
output is my usual Writer object name to write to a text file. I cannot find anything on this. Even searching "postfix completion" in the discussion board comes up with 0 results.

Thank you.
