Xfinity DVR question

I currently have tivo roamio with a Comcast cable card. I manually record certain local channels each month in 6hr blocks. I have to set up a manual recording for each. All

works good

while I know cable cards are still supported by xfinity, I imagine they won’t be in the future & totally discontinued at some point.

therefore, I would probably get an xfinity box. Does Comcast’s equipment offer some kind of manual recording (6hr blocks)? Assuming it would be a cloud DVR, but maybe not.

if so, can I use a mobile app and/or pc of some kind to schedule these 6hr manual recordings?

just wondering before my cable cards become totally extinct
