How to prevent Jade case when to transpile every case? PS: I'm using includes

I'm working on a very large project, using gulp, node, jade templates and bem notation. When trying to locally serve the app, I have one file causing it to take around 4 minutes to compile!! I noticed this file, if commented out, reduces the load time to 24 seconds!

The file in question (that I need to improve/refactor) has a case/when and includes lots of things. It seems that jade renders every include to javascript FIRST and then looks at what files we need or not based on the case... This is the file, is there a way to improve this? THANKS!!

// START sos-shopping-overlay/shopping-overlay

include ../../_bem

-var $prefix = 'sos-'

+bemto_scope({prefix: $prefix})
        +b.component
                .common-vertical-align
                        .common-vertical-align__content
                                +e.overlay
                                        +e.A.close(href="#", title="Close Overlay")

                                        case $sosType
