Clickonce Applications and dll

I have a lovely ClickOnce application that is using an equally lovely dll that is about 10MBs… Every time I publish this application a folder is created in the Application Files folder with the version and the files required. My question is: is it possible to change the path of the dll and have it like one or two levels up so that I don’t have to upload each time the same dll and end up having 1_0_0_42 x dlls on my ftp server? Thank you for reading me.
