If you have numbers that varying between million and hundreds of thousands it would be good to show the numbers with a thousand separator like in excel
You should be able to do this using the "Format:" setting under the Modeling ribbon, where you control how data displays. I'm not sure why you would want to do this on a visual by visual level, as that would just create more maintenance hassle. I'm not aware of a way to show an alternate thousands separator though, that could be really nice to change (or have it pick up from your Locale setting).
