Question about Titanium Media Sync (TMS)

[flroots]

I've been using Titanium Media Sync (TMS) for some time syncing one way continuous via FTP to my Windows 7 PC. I've encountered a real nuisance which I hope is solvable. Basically the phone and PC are always on the same LAN, but the LAN may change from time to time when traveling. I've found no easy way of modifying the account with new IP address of PC. The PC does have a name on the LAN. I'm wondering how to specify the name (within TMS) instead of the IP address. That way the phone would always find my PC. At the moment, I must delete all the sync'd folders and the account and start over with a new account and set of folders. This also requires deleting all the previously backed up data from PC. There must be a better way! Suggestions appreciated.
