Shortcut to declare variables in PL/SQL

For Java, IntelliJ offers the var postfix completion that allows me to assign an expression to a newly created variable.

"some string".var becomes String s = "some string";

Is there a way to achieve something similar for PL/SQL so that

BEGIN
'some string'.var
END

becomes

DECLARE
    s VARCHAR2(100);
BEGIN
    s := 'some string';
END

?
