Cascading or Tiling all windows for an application

Is there a way to auto tile or cascade all windows for an application? Would be cool to be able to use a gesture that would automatically tile all windows for the current application in focus snapping them all to predefined areas.

Is something like this possible with the current feature set in BTT?

no sorry, something like this is currently not possible with BTT and probably won't be added in thr near future. There are some tiling window managers for macOS but I'm not sure whether any of them works really well.
