Allow use of 3rd party dns block lists

I have manually entered over 100 domains to the network block list. 99% of them are trackers and ad-servers which the Eero Pro 'ad-block' feature is not catching. I would love to be able to configure the router to pull a custom block list from a provided URL or point it to a 3rd party ad and privacy block list service. If this is not technically feasible due to file size / memory limits on the Eero device, then offer some 3rd party block lists we can select from as an enhanced ad-block / privacy feature. Right now, I am solving this by using a custom dns service but it would be great to have this built-in to the Eero Plus features.
