Unrar specific .rar file from multipart list without automatically iterating through the list

I was wondering, since executing unrar -x file.part01.rar 123.zip destinationPath would automatically iterate through the list until the file 123.zip is found, is there a way to stop that auto search for multivolume archives? For example, I have a set of 100parts of a multipart volume, it would take some time to find the file if the file were to be located at part51. Instead, I would like to generate two processes that starts at part1 and the other starts at part50. If I were to execute unrar -x file.part50.rar 123.zip destinationPath, it skips part50 and starts over to the top. Second option, if possible, is there a way I can just execute unrar -x file.part50.rar 123.zip destinationPath and if file is not found exit/stop process and start a new command execution unrar -x file.part51.rar 123.zip destinationPath. Any suggestions or advice would be very much appreciated. Thank you.
