I doubt there is such a feature. This exists in Fireworks purely because Photoshop is the industry leader. Fireworks is not.

You could try exporting as paths to illustrator assuming that Fireworks can use them? AI Illustrator files are fairly well supported by many apps.

Either that or you could search around and maybe find a plugin that'll let you do this, as I'm sure someone else might have had the same sort of problem.

Alternatively, you can look at it the other way - What can you do in Fireworks that you can't do in Photoshop? Maybe there's a plugin for Photoshop that'll let you do that?
