Yes it is:

     @(<filename>:E=<filecontent>)

Will create a file and populate it with the content given. Then the 
@(...) is replaced with the name of the of the file in the action. There 
are other options possible not worth mentioning now. Instead I'll make 
sure to add some documentation for it :-)
