Hi Sachin,
i think regular expressions support is more for attack signature definition and pure sessionid.
when playing with entity (url, parameter, coookie, file type)
What you have in your example is a dynamic url, not a session id. So you can only use wildcard concept with limited function:

Wildcard CharacterDescription
"*"Match all characters
"?"Match any single character
[seq]Match any character that is in the specified sequence
[!seq]Match any character that is not in the specified sequence
