How to supply the absence of the TTreeView LoadFormStream in the Delphi RAD XE10 MultiDeviceApplication?

I have been trying to give a LoadFormStream to TTreeView so that it loads the data of a TStringStream in Delphi RAD XE10 MultiDeviceApplication mode, but I noticed the absence of this option ( TreeView1.LoadFromStream(StringStream1,Tencoding.ANSI); ) that it has as characteristic load data of a StringStream of categorically organized form in items and sub items as far as TAB's. How can I overcome the lack of help from LoadFormStream so that TTreeView is as in the image below?
