Time reference curve problem

Hello,

I have a situation where I need to do a 5s measurement file and use it as a reference to the next measurement. The problem is that the trigger may be armed anywhere between 1 second and 5 minutes, and the measurement file adopts the relative time base of the file. So the curves do not "line up".

Is there a way to set the relative time 0 from the trigger instead of arming the trigger?

Thanks in advance.

UPDATE->

I just found out that there are 2 different import functions, one for the data files and one is a module of the analyze section. So I found my needed functionality.
