+| attach-as      | No       | Optionally override the meta filename set when there are attachments.  Each attachment by default gets posted as `file01`, `file02`, etc.   There have been use-cases where someone's end point expects the meta name (where the file is found on the HTTP request) to be named something specific such as `document`.  Utilize this over-ride to accomplish such a feat. Also use the `*` character to allow the numbering.  Hence `?attach-as=meta*` would cause Apprise to store the files as `meta01`, `meta02`, etc.
 
 **Note:**: If you include file attachments; each one is concatenated into the same single post to the upstream server. The `Content-Type` header request also changes from `application/x-www-form-urlencoded` to `multipart/form-data` in this case.

+### Attach-As Over-Ride Options
+This section expands further on the `?attach-as=` override option.
+
+Simply add this to the URL: such as:
+```bash
+# apply the override of `file{:02d}` to be `document`
+bin/apprise -vvvv 'forms://webhook.site/<webhook>?attach-as=document' \
+   --attach test/var/apprise-test.png -b test 
+```
+
+In order to support other variations, you can do : 
+```bash
+# Set the file array object in the request as `{:02d}meta`
+bin/apprise -vvvv 'forms://webhook.site/<webhook>?attach-as=*meta' \
+   --attach test/var/apprise-test.png -b test
