OpenAtlas

I need some help with some of the references I've put into OpenAtlas. Alex made some changes to address this previously, but there are more references that need to be altered.

As before, instead of adding all references to one existing reference, I was creating individual references with each input. Can you do large-scale change to put all relevant references within one reference? Like this example: https://connec.acdh.oeaw.ac.at/entity/5341#tab-source.

So there should be only one reference to:

" 'Saint Augustine Letters volume 1 (1-82)', trans. by Wilfred Parsons (Washington: The Catholic University of America Press, 1951) " 
    " 'Saint Augustine Letters volume 2 (83-130)', trans. by Wilfred Parsons (Washington: The Catholic University of America Press, 1953) " 
    " CSEL 34.1 " 
    " CSEL 34.2 " 
    " CSEL 44 "

With " 'Saint Augustine Letters volume 3 (131-164)', trans. by Wilfred Parsons (Washington: The Catholic University of America Press, 1953) ", there are some individual entries that need to be moved, but there is also a master entry with 55 references here: https://connec.acdh.oeaw.ac.at/entity/3204.
