How to configure BBWin to send to multiple XyMOn servers on non-standard port

It is possible configure BBWIn to send
a) to multiple XyMon servers on standard 1984 port
        <setting name="bbdisplay" value="85.31.zzz.nnn 195.130.xxx.nnn" />
b) or send to 1 XyMon server on non-standard port 
        <setting name="bbdisplay" value="85.31.zzz.nnn:1999" />

Is it possible to have multiple servers with non-standard port?
        <setting name="bbdisplay" value="85.31.zzz.nnn:1999 
195.130.xxx.nnn:1999" />

Tested some combinations, but without success:

1)
C:\app\BBWin\bin>set BBDISPLAY="85.31.zzz.nnn:1999 195.130.xxx.nnn:1999

C:\app\BBWin\bin>BBWinCmd.exe %BBDISPLAY% query REPSERV01 cpu
bbdisplay defined to : 85.31.zzz.nnn
port defined to : 1999 195.130.xxx.nnn:1999
Sending query ...
hostname defined to: REPSERV01
Error : can't understand proxy host

2)
C:\app\BBWin\bin>set BBDISPLAY="85.31.zzz.nnn 195.130.xxx.nnn:1999

C:\app\BBWin\bin>BBWinCmd.exe %BBDISPLAY% query REPSERV01 cpu
bbdisplay defined to : 85.31.zzz.nnn 195.130.xxx.nnn
port defined to : 1999
Sending query ...
hostname defined to: REPSERV01
Error : can't understand proxy host


Any ideas?

P.S. BTW - when new bersion of BBWin is coming?
