Support for sub environments - possible enhancement

in SOAtest
While the environment structure is great, it would be beneficial if there was an ability to next these such that everything for a dev environment is set in a parent env, but divisions or such could be children to that parent, or viceversa.
ie Dev Environment
baseurl - http://dev.org
urlpathA - /endpointA
urlpathB - /endpointB
Then divisions specific sub-environment
DivisionA
Authorization - ;lsdkhfahfiousbavdalsd
securityToken - dev-divisionA-laks;dfjha;shg
enabled - TRUE
DivisionB
Authorization - ;ksjdhfasuhasdfljkhaklj
securityToken - dev-divisionB-sadlfknl;ansd
enabled - FALSE
