如何在golang Beego模板中的多个切片上应用范围？

I have a struct, containing two slices with same size, which is to be passed to the template.

type V struct {
    Process         []string
    ProcessType     []string
}

I need to iterate the slices in same range. In golang(without a framework) we could do this as follows

//I know all of you know this. Added for better understanding of my problem.
{{range $i, $e := .Process}} 
    {{.}} 
    {{index $.ProcessType $i}}
{{end}} 

We could apply range on a slice in beego like this

{{range $key, $val := .vm.Process}} //this.Data["vm"] = V (Struct V is passed as vm to the template)
    {{$val}}
{{end}}

How to include slice ProcessType in this range too?
