Reference in multiple steps

[jjangga0214]

It seems grunt-include-replace does not support deep reference.
The code below fails.
Does it have an update plan for this feature?

<!--base.html-->
<ul>
    <li>@@a</li>
    <li>@@b</li>
    <li>@@c</li>
</ul>

<!--foo.html-->
@@include('base.html', {
"a": @@a,
"b": @@b,
"c": "This is constant"})

<!--bar.html-->
@@include('foo.html', {
"a": "This is constant",
"b": "This is constant"})

P.S

Thanks for letting me enjoy replacing variables anyway :)
