SEP - how do I install defintions for a given date

I am developing a process in which a vendor I am working with will give me the date of the virus defintions I need to use in SEP.

for example: I need to install the SEP defintions from this date:

2013-11-18 rev.2 

I have my Liveupdate server configured to download content to a network folder. My thinking is, I am going to copy the files I need out of the Liveupdate directory and copy them to a directory where the SEP Manager will see them. What files do I need from that download

to utilize the defintions from that day?

Is it only files with this in the filename?   131118002

this format breaks down:

13 year

11 month

18 day

002 revision

any help would be appreciated.
