Hello and welcome to Numista!
In short, no. Not yet.
I would say: no. Never.
Unless both sites standardize their databases, but I see them as concurrents.
If that was possible, any of the sites could download the entire database and all the work already done for free.
Since there are obviously money involved, I don't see that happening.
