Output arguments from App Designer?

I'm trying to get my designed app to return a two element vector to my main workspace when it has a button pushed, so I can use it later in the main program. I found mention that it was an issue that would be resolved in R2017b, but I haven't been able to find any documentation on it, other than a reference to including a public function as a work around. Help with either approach would be appreciated. Using R2017b.

Thanks!

It's mentioned briefly on the link below, and there was another ride mention, but I couldn't find it again.

This MATLAB Answers thread discusses about Input arguments, no mention of Output arguments.

You can use the assignin to save the variable in the base workspace and use it later.
