Making Filter Options show only 1 copy of non-unique values

Hello! I am displaying a filter for one of my fields, a Select box, using a code like this:

	info.AddField("Tenant ID", "tenant_id", db.UUID).
		FieldFilterable(types.FilterType{FormType: form.SelectSingle}).
		FieldFilterOptionsFromTable("apps", "tenant_id", "tenant_id")

Because the values are not unique, the result looks like this:

Is it possible to make it unique, to display only one copy of each unique value?
