In general, no you can't submit multiple trajectory files and have them 
concatenated magically. Some utilities like trjcat will accept them, but 
only to write the concatenation, not to analyze it. Your options include 
hacking the source code of the utilities you want to use, getting a new 
file system, reducing the frequency of the data in the existing files 
using trjconv, not writing data so frequently during the simulation or 
using different analysis tools.
