TestStand does not have a specific feature to address the renaming of sequence and updating other sequences that are loaded at a later time.
I do not know what version you have, but TestStand 3.0 does have advanced find and replace options that allow you to search multiple sequence files for values. You could search for the sequence name and limit the search to sequence call steps. The find and replace result window lists all the possible changes to make
