Shimano SLX levers without bleed port at the lever end?

I am trying to bleed SLX brakes. There are 2 wee screws holding the reservoir cap on. Does this mean I have to get it level and bleed it down the way, rather than pump the fluid up from the caliper end with a syringe, making a mess? I can't see a bleed port at the lever end as appears to be in most of the you tube videos on the subject. Older model perhaps? The system when you screw a container into a bleed port looks great, but doesn't seem to apply in my case?

Most SLX have a large and a small screw, you replace the large screw with the funnel.
