certification for my cath lab to be predominantly a radial cath lab

There is no “radial” certification that I am aware of and I am a member of the SCAI Governance Council.

Question: 

Are you aware of how can I get certification for my cath lab to be predominantly a radial cath lab? 
Is it true that we have to do at least 20% transradial to get that certification?
The SCAI cannot answer this question.
Thank you.
