(App Designer) Can I trigger a callback or event when the user switches tabs?

Background: I'm using App designer to build a GUI. Currently, I have a few tabs in my GUI. One tab is dedicated to translating and creating test locations ('Translation' tab). The test locations are saved in a ListBox using the Items and ItemsData properties. Another tab ('Testing' tab) is dedicated to running a test at one (or multiple) test location(s).
What I would like: When the user switches to the 'Testing' tab, the 'Translation' ListBox Items and ItemsData properties will populate the 'Testing' Listbox's Item and ItemsData properties. Basically, when the user switches tabs, they will see the saved test locations from the previous tab.
Notes: I thought I could add a callback directly to the tab. But the only callback function suggested by app designer for is a 'size changed' function. (picture attached)
I can see at least 2 ways to accomplish updating the 'Testing' ListBox without triggering on a tab transition, but I just wanted to know if it was possible?
Thanks!

The tabgroup in which your tabs reside should have the callback that you're looking for: SelectionChangedFcn. It is called whenever the user changes the tab. There you can query what the newly selected tab is with the tabgp.SelectedTab property, and update your listbox if desired.
