User Filter detail with custom parameters

Hi Team, 

There is any way to use this function to filter details using a variable in the value like the role of the user for example?

Terrasoft.sdk.Details.configure("Case", "ActivityDetailV2StandardDetail", {
	filters: Ext.create("Terrasoft.Filter", {
		type: Terrasoft.FilterTypes.Group,
		subfilters: [
			Ext.create("Terrasoft.Filter", {
				compareType: Terrasoft.ComparisonTypes.NotEqual,
				property: "Type",
				value: Terrasoft.GUID.ActivityTypeEmail
			})
		]
	})
});
