Property Actions - does this still exist in Standard Omnigraffle (i.e. not Pro)?

I tried out the free version of standard Omnigraffle in Oct 2013 and at the time it had the feature “Properties: Actions”. An example of what this looks like can be seen in this tutorial:

I bought standard Omnigraffle 6 (currently on v6.0.5) recently which looks a little different than the version I tried out at the end of last year. However - I can’t find the the “Properties: Actions” feature on standard Omnigraffle 6 - has this feature been renamed and relocated somewhere else? Or does this feature no longer exist in standard Omnigraffle 6?

This is a Pro-only feature in OmniGraffle 6. It can be found on the Properties tab:
