Can I use C++ api version (CNeroIsoEntry, ...) to burn multisession?

Looks to me that this is a solution for solving timestamp problem. In NeroApiTest, Nero is using c++ calls for burning files / directories. Question is, can I attach files from previous session(as files from previous session are returned as NERO_ISO_ITEM), to CNeroIsoTrack using CNeroIsoEntry? Looks to me like the answer is yes, if so how do I specify that a CNeroIsoEntry is from e previous session?
