This might help in what you are trying to do.
Open up the .seq file with a formatted editor such as Wordpad, and copy contents and save them to a new .seq file.
Do the same with the other .seq files and paste them to follow on the others.
Just remember to rename the numbers shown as [1] etc with the correct number.
This will give you one .seq file with all your cues.
