S4HANA Workcenter Hierarchy App

Hello All,

CR21, CR22, CR23 T.Code apps for creation and change of workcenter Hierarchy was available on the S4HANA App library till the release 1610. But after that we cannot call these T.Codes via SAP Fiori Launchpad, instead we can create and change a workcenter hierarchy via GUI only.

I was not able to find any specific alternative app as well in the Fiori Library. Does anybody knows, if there is an alternate way to create a workcenter hierarchy via Fiori Launchpad?
