it is. But it's not the same on every device. On XZ2 you press and hold on the app and then just drag it to the top of the screen. I'll check how it is on xperia 10. Because, they are both sony, both run pie but the launcher is not the same. The most obvious difference are gesture support. And BTW those android gesture sucks, I switched to regular buttons. And I do miss gestures from sailfish
