differentially methylated bed file from encode

Question

[ccagg]

I am looking to compile all the tissues profiled in the ENCODE WGBS and RRBS experiments into one matrix, and find all the differentially methylated regions, which has turned out to be a monumental amount of data. I'm looking for something similar to the roadmap fractional methylation calls found here

I realize that I can't be the first person to want to use DMRs from this dataset- I have seen many papers on it. However, I can't seem to find this processed data anywhere. I can only find individual bed files. Does anyone know where I can find a matrix like this? I would be very grateful for hours of saved time!
