Assigning Window to Specific Desktop

I would like to have a quicker and easier way to assign windows to a specific desktop, but am not finding a straightforward way to do this in BTT. Appologies if I am overlooking a simple way to do this, but any help or direction on whether this is possible would be appreciated. TIA.

(n.b. I am already using shortcuts for moving windows quickly. Edit: Though, once I plug into monitors, sending a window to a specific desktop no longer works.)
