I have “projects” - “topics” might be a better word, identified by hashtag, like “#home/bathroom/remodel”
Things happen related to this topic during the day - emails, phone calls, ideas for Todo items, etc. Multiple topics are active at any one time.
When they happen I open the daily journal and add a bullet list item, with the hashtag, possibly with nested items. Something like
```
- #home/bathroom/remodel Call from [[Acme Contractors]]
- Agreed start date of 2026-06-01
- They will send invoice by end of week
- Confirm invoice received from [[Acme Contractors]] 
2026-05-15
```
There are a couple of things I want to do with this data:
1. On a “master page” for the topic I want to create a “Journal” heading that contains just the list items (and any children) tagged with that topic. This gives me a chronological overview of everything that’s happened on this topic.
2. On a “master page” for the topic I want to create a “ToDo” heading that contains just the todo items tagged with that topic (or where any parent list item of the todo item is tagged with the topic). Tasks in this section should be “active” (i.e., I should be able to check them off, change the due date, etc, and this is reflected back on the relevant journal page).
Is this possible? Dataview queries don’t seem to be powerful enough (e.g., forum.obsidian.md/t/dataview-query-to-extract-a-list-item-and-all-its-sublist-items/78291/2), although that discussion is now more than two years old, so functionality may have improved?
If it’s not possible, does anyone have recommendations for ways of working that:
1. Allows me to quickly capture updates on topics without having to navigate through the vault.
2. Collates those updates into a single page.
