Custom Field Polynomial in Reed-Solomon Encoder

I'm trying to create a Reed-Solomon encoder to generate ECC words for SMPTE 299M embedded audio.  

 

The polynomial is x^6 + x^5 + x^3 + x^2 + x + 1. 

 

These are the parameters I need: 

 

Bits per symbol: 8 

Symbols per codeword: 31 

Check symbols per codeword: 6 

Field polynomial: 111 

 

When I choose the first three parameters, the Field Polynomial dropdown box starts at 285 and goes up from there. 

 

Is there a way to get 111 in this field?
