Reuse a Regexp token

I have a sorting rule which should match on multiple patterns, like "aaaa {title}" and "bbbb {title}".
I created the first criteria, and told the rule to use the custom title token to create some tags and stuff.
Now i am stuck in creating the second criteria. I cannot recycle the title token from the first one, can i? Because it is not listed in the match filters, nor in the custom ones in the second criteria.
I _could_ however create a second token with the same regular expression as the first one, and name it title2 or something.
But then i don't know how to differentiate between both tokens when creating the tags. Because some files have the title token attached, and some have title2...
To cut a long story short: How can i reuse a custom defined token in multiple criterias for the same rule?
