How can we update a project log on the slave?

Our build verification test performs a large number of test cases on the AUT and the projectsuite logs are emailed as an MHT attachment upon completion. We developed an XML file containing applicable data which is parsed during test execution on the slave/Test Execute. The TestComplete master runs the test via a single testitem that calls a networksuite task but with this approach, despite 50-60 tests running for 1.4-1.5 hours and upon completion, since the Master has only a single test item, the project log shows only 1 test which despite no errors, typically contains several warnings due to non-critical;existing defects/bugs with the AUT, so TestComplete classifies as a failure in the log. While I have seen several threads and support articles on parsing log files for custom logging and have added NetworkSuite variables for tracking the number of test cases, warnings, and errors. So what I am trying to find out is if it is possible to programatically update the applicable child nodes in the 'Description.tcLog' xml file prior to export?
