Is it possible to send url to the file in call to sessionappendv2 or sessionstart. The reason is that whenever I try to upload files in sequence, I am getting memory leaks in node, becase it keeps the result of reedFile() in memory, which I must call sequentally. If sum of all parts of splitted file is bigger than 500mb it throws `FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory`
