How to change selectivesync folders remotly in a client

Hello everyboby,
When I am not at home I need sometimes to change the selectivesync folders of my local client. Can I do it remotely without the gui?
PS : I tried to modifiy the .sync…db but the configuration comes back to the original one after ~10mn and I don’t see the config file in my client, neither in the doc.
Thanks in advance.
