Coverage filters

Hello, I'd like to set the coverage filters dynamically via command line, or m-file, but it seems that no APIs have been released to this purpose. My idea is now to 'simulate' the right click, with the relevant selection of the exclusion of a certain block. Is it possible? And how?

Thanks MC
