How Can I Use Release Management To Remove \ Add Change Web.Config Tags?

As everyone knows , in VS2010 and above there is a use of Web.config transforms to remove add update tags and attributes in a web.config file .

Release management has the ability to switch values inside a web.token.config (convention is a variable like so : ConnectionString )

but what do i do in order to remove a whole section ? or add one for a different environment ? for example , qa should not have a debug option , so in transforms we could Hide Copy Code

i really am trying to connect between transforms and release management but can't , they do not behave the same , a single build definition must know which web.config file to use (i use web.QA.config and web.prod.config) , while release template has only one build definition for both his qa and prod paths .

so , one release template with 2 stages (qa->prod) which has the same build definition cannot transform once for qa and once for prod (because again, it is defined in the build definition , from where to transform like Hide Copy Code

:/p:UseWPP_CopyWebApplication=true /p:PipelineDependsOnBuild=false /p:Configuration=QA /p:TransformConfigFiles=true

i tried this link http://ift.tt/1KNIgBD[^]

but it does not help the build definition transform the right web.config according to the release path . he just build the web.release.config , which does not help .

i tried many other sites as well , non of them answers the simple question : how can release management transform the web config file beyond just a simple value swap , which is not enough in my scenario , how can it add tags , remove them change deeper configurations .
