Floorplan Help

I am relatively new to HA, And i am really amazed with the Power it has,

I have created a floorplan using inkscape. I needed some help on more that 1 icon in floorplan lighting up when i press 1 switch.

every ID needs to be assigned a Specific entity ID from HA which i have done.

Now i have my gate lights that i have added in the Floorplan, I have only 1 switch (entity) for it, So how can i use 1 Switch to show this on my floor plan which lights up both my gate lights.

Steps would be really helpfull.
