yesod run-time hamlet template

I am working a web app based on yesod( without scaffold ). While, with the code become large, it consumes a lot of time when I make a small change in the [whamlet||] and $(hamletFile ..) quasiquoter because my app need to be recompiled.

So I use the Text.Hamlet.Runtime to include my template file at run time. Now, My sample code looks like this:

#ifndef EMBED
    render <- getUrlRender
    let css1 = render $ StaticR res_css1
        css2 = render $ StaticR res_css2
        out = render LogoutR

    let interp = Map.fromList [("css1", toHamletData css1), ("css2", toHamletData css2), ("LogoutR", toHamletData out)]

    tmpl <- renderHamletTemplateFile defaultHamletSettings "tpl/site.hamlet"
    page <- renderHamletTemplate tmpl interp
#endif

It seems that the function renderHamletTemplate does not support interpreting url route, so I change my template:

@{StaticR res_css1} to #{css1}

@{StaticR res_css2} to #{css2}

@{LogoutR} to #{LogoutR}

Now, it works for my app, and the #{css1} , #{css2} , #{LogoutR} is interpreted to what i expected in my "tpl/site.hamlet" file.

But, It is a little bit ugly code that I must have a copy of all my template file, just make a little transform to work for me.

How can I just use one template file to work both in compile-time and run-time?
