How to use alternative combined fragments in Visio 2007?

Question

I have been spending looking for how to use alternative combined fragments in Visio 2007 for UML sequence diagram, but it seems like there is no notation to create this if-then-else statement.

(like the following in visual-paradigm: http://knowhow.visual-paradigm.com/?p=788)

Is alternatives supported by Visio 2007? (otherwise, how do we create if-then-else block in Visio?)

Thank you very much

Solution

Found solution!

Visio uses UML 2.2 and hence does not have alt. box.

However, there are plugins for Visio all versions here: http://softwarestencils.com/uml/index.html There are alt. box shapes included.
