Fixing Nios II custom instruction numbers

Does anyone know if it is possible to give custom instructions fixed numbers? 

This seems to have been done for the ones that support FP, but doesn't seem to be present in the SOPC builder. 

 

Assigning the instruction numbers myself has significant advantages when there are multiple cpu with different combinations of custom instructions and/or code is being compiled outside of the IDE and SOPC.
