I think you can from the app, but not from the website.  I'm not entirely sure though, as I've never tried it either.  I just leave the drafts blank mostly for efficiency (and I like to save them for later so I can easily keep track of how many I've done).

Huh.  That's weird.  I wonder why that is.  Although, now that you mention it, there was a recent event that was archived near me but it still shows up on the OFFICIAL app, which is definitely not supposed to happen.  So I wonder if that's an issue generated on Groundspeak's end with the way they archive certain caches.  (I noticed that the one archived event near me that kept showing up was archived by HQ, rather than by a local Admin or the Event creator... I wonder if that's somehow relevant).

I'm not sure how practical that would be, primarily because in most cases with letterbox hybrids you don't actually end up with corrected coordinates.  With mystery and multi caches, the final answer is usually just a set of coordinates that you plug in, but with letterboxes you're usually just following instructions, so unless you get to the final, take your own coordinate reading with your device at GZ, and then add in those coords, you're not likely to actually get corrected coordinates.

I was out caching today and found five caches. I logged each of these as finds and at the end of the day I had five Pending Geocache Logs (waiting to be posted as field notes).
It doesn't look like there is a way to upload all of these field notes at one time rather than one at a time. Is this correct?
Are there plans to include a way to upload in bulk? It doesn't take too long to upload five caches individually, but it might get a bit tedious if one has 20 or 30 finds waiting to be uploaded as field notes.
 

Letterboxes are not necessarily at the given location.  A "true" letterbox usually requires following some set of instructions to find the final cache location.  A letterbox hybrid can be set up either like a traditional geocache (where its hidden at the given location) or it can be set up like a traditional letterbox (where its NOT hidden at the given location).  You can't really tell which way any given letterbox is hidden without reading the description.
