[sudo-users] sudoers file - Limiting command line argument

[b. nyec]

Hi, 

I know this has been asked many times, but i am unable to find a solid answer/solution. 

I just need to exclude or restrict one or two command line arguments from an allowed command. 

Logic: 
Allow the command /path/to/command to be run with ALL arguments except for "-a" and "--argument" 

So for example, 
/path/to/command -myarg bla -secdarg bla2 - would be allowed
/path/to/command -myarg bla -a -secdarg bla2 - would NOT be allowed 
/path/to/command -myarg bla -secdarg bla2 -a - would NOT be allowed
/path/to/command --argument -myarg bla -secdarg bla2 - would NOT be allowed
etc.... 

What would be the regex for something like this? trial and error, i'm not able to get it to work properly. 

I have seen suggestions a little less elegant of creating a "wrapper script", would this the only real alternative/correct way ? 

Thanks for you time.
