7Zip add string to zip name

Question

I have a 7zip command line process that zips by date and its works well. The command creates a zip file with date IE 20121019.zip. However Id like to add a string to the file name. for example 20121019_PRIMARY.zip.

Here is my current command

"c:\Program Files\7-Zip\7z.exe" a
 x:\Logs\HS\%date:~10,4%%date:~4,2%%date:~7,2%\%date:~10,4%%date:~4,2%%date:~7,2%.zip
 X:\Logs\HS\%date:~10,4%%date:~4,2%%date:~7,2%\* -xr!*.zip

Answer 1

Can't you just use

c:\Program Files\7-Zip\7z.exe" a x:\Logs\HS\%date:~10,4%%date:~4,2%%date:~7,2%\%date:~10,4%%date:~4,2%%date:~7,2%_PRIMARY.zip X:\Logs\HS\%date:~10,4%%date:~4,2%%date:~7,2%* -xr!*.zip

instead, or have I missed something?
