No.
Another, accessing filezilla site name from WinSCP, in my previous post I mentioned the syntax I tried to achieve
a. Filezilla command line not working for us. ( filezilla has limited on CLI)
b. Filezila is working fine with Proxy with Site1. We tried to set up the same details on WinSCP not working.

You can import sites from FileZilla:

I can provide you a development build of WinSCP 5.10, if you contact me on my email address.
