I first tried with comphelper::dispatchCommand(), which I had seen in 
tiledrendering, but that did not know the needed SID. Now I have used
pViewShell->GetViewFrame()->GetDispatcher()->Execute, which I have seen 
in uiimpress, and that works.

Yes, that is suitable. It has already some undo parts. My patch is 
finished now. Find it in https://gerrit.libreoffice.org/#/c/82367/2
