2 Servers 1 FTP

Subject says it all.
i am hosting 2 GMOD servers but have only 1 ftp.
server 1 = Sandbox
server 2 = spacebuild
how would i make this work?
I have an idea whitch is to rename the sandbox server “orangebox\garrysmod” folder to “orangebox\garrysmodsand”.
As well as rename the spacebuild server “orangebox\garrysmod” folder to “orangebox\garrysmodsb”.
and do the same on the ftp server.
Would this work? if so please tell me asap and if it wont please give me other options.
thanks in advance for the help
