Given:

1. A tendency of massively marking all items as schedule [1]
2. Some of that items should be done on daily basis (I generate them 
with a daily template and the power of org-capture)
3. Life happens and some of them are accumulated, for my last case, that 
was 29 entries pending to be processed

Action:

I procedure with a batch action for that 29 entries (imagine here a 
batch script), and now that it is done, then I need to clear it up from 
my org-agenda

org-agenda-bulk-action  [2] does not serve me because it marks the TODO 
thing without a note, and it's not possible to add a note with the 
prefix. Going to offtopic, I also discovered that does not respect the 
enforce-todo-dependencies [3], ignores if that entries have child todo 
items.

I tried to create a org-agenda-bulk-custom-functions but I failed 
because I wanted a chosen state and a shared note for all the bulk items 
and the way that functions work cannot be done.

But the bulk items are in a variable (nice), 
org-agenda-bulk-marked-entries, and you can traverse it with a generic 
function, so I did it. It took me, unexpectetly, 1h30m to get it working 
(and I could not find other stuff around), so I am sharing what I have 
done so other people can benefit, and by the way, I would like to know 
what do you think of that approach and if you have ideas to improve it.

See it attached in file org-agenda-bulk-todo-with-note.el

With that script I added a note of resolution of that items saying that 
it was resolved through my task with CUSTOM_ID/ID X (like when you close 
multiple issues in a ticketing software) [4]

A healthy 2025 for you guys,
