The CDM reflects what people need to do analytical use cases. The CDM is not the place to hoard whatever data might be available, but to serve a certain question. So, we need your use case, Vimala.
It certainly is possible and encouraged! Called the CDM Working Group. I realize it might be a little difficult for you to attend, given the timing. But you can definitely submit a proposal. We need a use case and the actual proposal. If you need help, let us know and we make it happen.
You may also join forces with @cukarthik and @bailey, who are proposing a similar desire.
