Export Composition as Text Template not available
I wanted to export a lower third as a Text Template. But the export option does not show up at all in the export panel.
So I can't export as .aecap file.
AE release: 2017.2 (14.2.0.198) Updated today May 1st 2017
OS. Win10
Here's a screenshot of the available options in the export submenu.

Did I miss something? But I thought this is the way to go now.
