[CentOS] Deleting packages

When choosing to delete packages, Synaptic will tell the user what other 
packages are dependant and therefore have to be added to the delete list 
also, and then will automatically add those dependant packages to the 
delete list if one chooses to go ahead with the original package 
deletion. I did not notice such functionality in YumEx. Does it exist ?

If it does not exist, is it possible to use Synaptic under CentOS 4.4 
with the rpm repositories and have it work correctly ? In general I like 
the Synaptic interface and functionality better than the YumEx 
functionality. I do understand that there is an updated version of YumEx 
for Yum 3.0+, but since CentOS is still on an earlier version of Yum, it 
can not be used.
