Reply to How to merge .tsi files

Anyone know a way to merge .tsi files? I know the old traktor tools used to work for older versions, but is there a newer app that will do this with current mappings? I have a launchpad mapping with 4 .tsi files and want to merge them into one. Also have two X1 mappings and want to swap things around from one to the other. Any help would be appreciated. Thanks.
