session import issue...?

hi!



I have an issue with the session import function.



i have multiple recordings made in different sessions, to mix those i want to have all of them in on session. as far as the audio files go, no issue. but i would like to take markers and tempo data for each song as well...



if i import a new song, protools over writes tempo and marker of the song being imported before. sometimes it even sets it to the wrong time code, audio is far right, markers far left.



is there any trick to make this work? having all songs including markers and tempo in one session?



thanks!
