It is, but it's officially unsupported (i.e. it may break in a future release) and a bit challenging; you have to use a Unicode text editor to insert the custom character code 0xEAB1 in each place where you want a newline. *Don't* just put the text EAB1 in there, use the menu command for inserting a special character / custom character and type in that character code. (once you've done it once, you can usually copy-and-paste it into the other places where you want newlines)
