It's not possible right now but you can cheat by making the link dashboard transparent and out it on top of another template. Then use RM or Smart lighting to tie them together.
Or hopefully a CSS guru will chime in.
(this was the best way I found to make it meaningful, Dashboard links still displayed the name)
Edit the CSS, through Advanced->CSS and add this for each virtual switch you added (change the coordinates accordingly) This example is Tile 1 is row-start= 1, column start= 1 and has a width and hight of 2. So row end =3, and column end = 3.
Many thanks for this detailed answer! I'm very close to successfully following your tutorial. However I can't remove the device name at the bottom of the tile.
I really don't know anything about coding so I might be doing something wrong....I just copied your code into the empy css field, replaced lounge with the name of my virtual switch and changed the coordinates.
After that when I click save the name of the device is still there though.
I too had some trouble wrapping my head around this. Especially with the 2nd set for different size tiles and then I kept moving them. So add Row + Height and Column + Width for the end tile position. Sadly, this was not so obvious for me at first as I'm sure it was for most.
That's crazy I was looking for the same feature as I too have a switch to tell ME if all doors are closed.
I again am looking for deep nesting of dashboard links.
Also it would be nice to change it's template use.
For example in individual dashboards to make a switch a dashboard link .
And just as dAnderson requested a per tile config
