Caja shortcut to open all subfolders

Caja drag and drop with tree view

I recently switched from Mint Mate to Ubuntu Mate. Generally I like it but would like to know if there is some way to get Caja to highlight the folder I am dropping a file into when I have tree view in the left panel. Mint Mate, XFCE, KDE all do this. I have attached a screenshot from XFCE. Notice the highlights on the New folder as I am about to drop the file in it. [Screenshot_2021-09-30_13-06-54]
