Not unless you look at each cache page of the caches you have found in the map area, the NGR is shown just under the N/W grid ref.
I received the new macro for 190, which I'm testing at the moment, today. Will be a while before the actual final cache is issued as I need to do the cache page, get it approved and place the actual final cache.
You could try it out on Yorkshire Yellow's Explorer 179 (GC4OOB8) as I guess you will have found a few down there.
