How to merge several separate PT sessions into one ?

[Chris7514]

Hi Everyone !
I need to find the solution to how to create one long session out of several separate sessions. There are four songs, that need to be put together one after another preserving all individual tempo maps, markers and all audio regions. The beginning of the second song will be for example in measure 97 right after the first song ended. How to import all data from that session, so the starting bar will be 97, and all files will relate to that beginning ? I wanna also keep measures numbers running ( 97, 98, 99 etc.).
Is it even possible within PT to combine several sessions ?
Sincerely,
