Using RegEx in Subscription Criteria

Question

Using RegEx in Subscription Criteria
Hello
I want to use RegEx expression for filtering in my Subscription criteria, as follows:
Let say all the monitor I created start with same set of characters i.e.
"My Monitor"
Therefore I have several monitors called
My Monitor ABC
My Monitor 123
My Monitor XYZ
Therefore as part of the Subscription Criteria, under "with a specific name" I currently have
My Monitor%
The % meaning any one or more characters. That works find I receive notifications for alerts from all of the monitors with the above names.
Now what I want to do is keep this one subscription criteria but exclude notifications from say My Monitor 123. I still want to receive notifications from the other two monitors, therefore I was thinking this is a case for RegEx
First question is can I use RegEx in the criteria "with a specific name" field? I guess I am already doing the with the % however, I believe that is an SQL expression rather than a true RegEx expression?
The following blog has some detailed information
http://social.technet.microsoft.com/Forums/en-US/operationsmanagergeneral/thread/ac0bf65f-f562-4f8c-b624-5fbe7ee2e795/
I am not clear if this would work in my case, for example it states the ^ character is used to denote NOT. Based on this I was thinking about changing the above
My Monitor%
To
My Monitor%[^123]
Will the above work, is it the correct syntax?
Any advise, most welcome
Thanks you all

Hello Yury,
Thanks again for your help. Your solution worked, however with a slight difference as I discovered something else while testing.
Basically the example above
My Monitor [^1][^2][^3]%
Only takes into account the First character of the word/phrase for example, using the above filer, the results were
My Monitor ABC - pass
My Monitor 123 - no pass
My Monitor XYZ - pass
My Monitor 222 - pass
My Monitor XY3 - pass
I therefore had to add an _ as part of the filter meaning one character, therefore using the above example if I want to block
My Monitor 123
My filter would be as follows
My Monitor [^1][^_2][^__3]%
i.e. 1 being the first character, 2 being the second character by placing any single character in front of it using the _ then 3 being the third character by placing and two characters
in from of it by using two _ characters i.e. __
Thanks again, I could not of figured it out without your help
