How to share execution result between different test phases in Testlink

Here is the query

I have test cases for Smoke test and Regression test, and smoke test is a subset of regression test. So, if i am getting a build-xyz for QA, first i will do the smoke test, and will update the result of those TCs. If all good in smoke, i will move to regression. As the regression test also has the TCs covered in Smoke test, i want the execution result i did on Smoke test phase to be available in regression phase as well. (As this will help me to avoid the duplicate work)

How can i see the regression TCs with the execution result from Smoke test?
