[TxMt] Open in tab from external program

[Kelvin Tse]

Hi,

I use my ftp client Cyberduck with Textmate, every time I edit a file  
(double click on a file in cyberduck), it will open a new window in  
Textmate, for every file I click on. Is there anyway to config  
Textmate so that Textmate can open files in tab by default?

Thanks

Kelvin
