Crosspost to my own write.as blogs as channels?

Hi Write.as community, I recently noticed the crossposting feature and it looks really neat!

One thing I’d like to do is to have each of my write.as blog contain a subset of my anonymous posts. For example, perhaps I have two blogs:

zus’ journal
zus’ productivity

I might make a post that can fit into either, both, or none of the categories. I’d like to essentially crosspost that anonymous post depending on which categories it goes into, and when I modify that anonymous post, it will be updated on each of the blogs that it’s been crossposted into.

This essentially feels like using each write.as blog as it’s own channel.

Is this possible to do currently? If not, is there any workaround? If not, I was wondering whether we can expect a feature like that to be added.

Thanks,
Z
