WRF WPS CERRA Vtable and variables transformation

Good morning, I'm wondering if there is foreseen to release any documentation or guidelines and Vtable to feed WRF with CERRA IC and BC. Thanks 

I have been reading comments on certain fora that suggest the there are issues with the WPS stage of preprocessing WRF data using ERA5 (released in 2018), specifically related to ambiguity surrounding Vtable variables, such as LANDSEA flags, SOILHGT, etc.

I was wondering if there was any additional information on how to avoid these problems?
