[Multi-KPI] Change the font-family in app theme json configuration file

[hadrienlp]

Hello fellow Qlik enthusiasts,

Like some of you here I am using a corporate Qlik Sense Enterprise on Windows  theme with custom color palettes, fonts, etc

I have an issue with the Multi-KPI object. I have been able to play around with its styling by changing properties in the "qlik-multi-kpi" object in the theme json configuration file like so :

"qlik-multi-kpi": {
		"backgroundColor": "transparent",
		"title": {
			"main": {
		    "color": "white"
			},
			"subTitle": {
			  "color": "white"
			},
			"footer": {
			  "color": "white",
			  "backgroundColor": "transparent"
			}
		}
	}

For some reason, multi-kpi objects do not take into account the global "fontFamily" property in the config file.

It means I have to define the font-family in every single multi-kpi object using css, which is a pain as well as being completely stupid since themes are supposed to take care of this.

I would like to define this theme wide, in the json file. The multi-kpi object properties are missing in the custom theme documentation so maybe I am missing something. 

Is there a way to accomplish this?
