I don't recommend using dynamic filters because they completely override any matching static filters. Makes the point of filter lists useless, if uBo had a way to set dynamic filters to a lower priority than static they might actually be useful. At the moment the only way I found to replicate uMatrix was to use static filters to block by default on a per domain basis and whitelist domains per request type. It is a lot more work so I only do so for sites with user generated content (e.g. hn or reddit) that have links to who knows where that you might want to prevent from loading.
