markers and edits

[tantejo]

hello everybody, i have a simple question ??
maybe it's in the the manual but i lost it some years ago.
on some sessions i record all the different songs after each other in the same protools session, because it's faster with mix setup and plugins etc. i make 1 setup and use that for all the songs. i create a marker for each song, but i want to 'lock' the marker with the beginning of each song, but i don't know how to do it. (if it is possible ??)
if i want to change song 1 and 2 i want the markers to follow. simple ?!
is it possible ? thanks !
