New Cross Instrument Pairs

[lzrbms]

Would it be possible to link the following instruments for the Rithmic cross instrument trading pairs?:

• SIL (micro silver) to SI (silver)
  
• QC (e-mini copper) to HG (copper)
  
• QG (e-mini natural gas ) to NG (natural gas)
  

Thanks!

Bump.

Apparently QG to NG works, but the other two (SIL to SI and QC to HG) don't work.
