regular expression on subdomain?

[itrixinc]

I have 3 servers that I would like to access based on regular expression
eg.
t1.......t10.sample.com --> 192.168.0.1:443
t11....t20.sample.com ---> 192.168.0.2:443
t21....t30.sample.com --> 192.168.0.3:443

Can someone guide how I can configure this setup?

Wildcard *.sample.com to a single server is not an option.

[itrixinc]

still stuck on this. Any pointers ?
