No, but DATAQ Instruments Hardware Manager can start two instances of WinDaq simultaneously, and by checking Edit Preferences Broadcast Sync messages in one unit and using File, Open in both you can start the other one recording at about the same time. However, their timing will probably drift apart over time, since each device has its own clock with a tolerance of +-50 parts per million or +-4.32 seconds per day. After the files are closed, the Advanced CODAS Copy Channel program can then be used to copy channels from the second file into the first file. Approximate synchronization can be provided by a program called MARKHOUR that automatically generates an event marker in all WinDaq processes at the start of each hour. In WWB, Search Event Mark on the first channel from each device can locate those marks.
