Can I add reverb a second time to the same mono track?

Version 2.3.0 on Windows 7, 32 bit. If I added reverb to a track, can I add it a second time. I tried it and nothing seemed to happen. I do have an older copy, but if I could do this, it would save a lot of time, Thanks!

Sure, you can “double-up” on the reverb by running it again,


If you want a realistic stereo-reverb , you’ll need to make a dual-mono version of your mono track,
and apply the reverb effect to the dual mono.
