Use metadata added by dataview plugin to filter tasks by creation day

[Oratoriooooo]

Hi, I see there is a workaround by add start date in todo to filter by creation date
but I'd love it to be automated, since manual adding data is cumbersome when working on heavy load multi-tasking.

proposal

dataview plugin automatically add metadata like file.cday when creating a note. documentaion
if we can filter by those metadata like below, it will drastically reduce human labor for people wanting this feature.

```tasks
undone
file.cday = today
```

Hi, thank you for the suggestion.

Searching for creation in the project shows that this is a popular request, and I would encourage you to upvote existing requests in Discussions, for visibility when I plan future work:

I note that you have spelled the new property file.cday and that is interesting to me.

I had wondered cday vs ctime vs file.cday vs file.ctime ... And whether if we used the file.... versions, people would then expect to also have file.path, file.folder, file.name... Whilst retaining backwards compatibility with the existing properties.

I believe it is not a priority now since I found a workaround using dataview to list all undone task based on creation date, group by file.path. however I cannot work out how to group by heading using dataview, which is also important to me and works great in tasks.

code

```dataview
task 
from ""
where file.cday = date(yesterday) and !completed
group by file.path
```

and it gives all tasks created yesterday, group by files:

for now I think you can let people know this method, if you cannot implement filter task by cday in tasks now.
maybe we can use dataviewjs to group by heading with code above, although I don't know how to write the code now. Or perhaps there is metadata for heading that I don't know. Here is what I know for now.

I appreciate the suggestion, but I'm spending all my free time documenting new things that Tasks can now do, so am unlikely to be able to do that any time soon.

Thank you for the information though!
