How to display Work Number from LDAP/VCard in buddy list

Is there any way to display the Work Number from LDAP/AD in the buddy list next to the name for example

Carl S (2218)

And or at least display in the VCard popup when you hover over the names. As it is now I can get the Work number (extension) by right clicking and choosing view profile.

I had been using 2.5.8 now I am using 2.6 RC2
