Goal Metric - URL Contains

I am looking to create a test and set a success metic using the Primary Goal of Conversion, where the user Views a Page determined by the URL Contains option.

Can i use a wildcard such as  /widget/blah?var=*123

Will it accept the use of the * and wildcard match this to anything provided the URL contains the other the other specified elements?

EG: /widget/blah?var=acb123 (this would be a successful match).

Thanks in advance
