Alternate paths in sequence diagrams

Hey all,
I have the Community edition of this program. I am trying to make up some sequence diagrams based on text use cases. Everything has been fine, except that i cannot figure out how to display an alternate path. I.e. if statements
From all examples in books i have seen, its merely a transparent box w/ ALT in the upper left corner. Does this option exist in the community edition?
THanks

Dear Jason,

This notation will be supported in the next release of VP-UML.

Regards,

Antony.
