how did you get org-agenda-bulk-mark-regexp to match categories?

in org-process-inbox you have

```
(org-agenda-bulk-mark-regexp "inbox:")
```

but this doesn't work for me. only the text of the actual to item is matched against

Start by reading the org-process-inbox entry containing the org-agenda-bulk-mark-regexp call and then inspect how that command matches agenda text versus categories. Reproduce the reported mismatch and determine whether the configuration or the command behavior needs changing; done means the category is matched or the required setup is documented.
