Wall Switch to Control Lamps?

We have two table lamps in our lounge. My wife switches the main light off and turns the lamps on. I hate having to go to each lamp to turn them off. I want an automatic or easier way to turn them off.

I have a Fibaro Dimmer 2. I want to install it so I can dim the main light, I was wondering if I got a two gang switch if I can connect the second switch to the Fibaro Dimmer and have it switch off the table lamps. I think you can do this with the Fibaro hub but not sure about Smartthings.Does it show up as an additional switch if it’s connected?

I was thinking the lamps would be connected to smart power outlets, or Osram Lightify bulbs.
