Is it possible to filter the news that will be received by a WebSocket, when signing up for a MRN_STORY *before* receiving and uncompressing the news received?
I ask that because otherwise one will have to receive, uncompress and filter each news which might not be relevant. If it would be possible to define that, for example, only news coming from the country 'US' with the language 'EN' would be received, that would decrease the amount of traffic and processing.
If this is possible, please let me know how; if it is not possible (which appears to be the case), then I would like to be sure of it!
