Lightroom: relocate originals

So, I'm aware that you can relocate specific folders from within Lightroom,
but I would rather relocate originals based on filters/collections.

In short, this is what I have now:

/Volumes/Mobile
- Lightroom Catalog
- Photos
- (year)
- (month)
photos

So I have a folder for 2015, 2016 etc etc.

Now, What I want is:

/Users/sandman/Dropbox/Pictures
- Lightroom Catalog
- Photos
- 2015
- 11
- 12
- 2016
- 01

/Volumes/Mobile
- Photos
- 2015
- 11
- 10
- (etc)
- 2014
(etc)

And, as you can note, the 2015/11 folder exists in both places - and the
reason for this is that in my dropbox folder I want to keep all photos from,
say, the last two months, which spans 20015-11-18 - 2016-01-18, so all
photos from 2015-11-01 to 2015-11-17 would be n /Volumes/Mobile

I certainly understand that this can't be done automatically, which is why I
have two smart collection:

"Recent" : "Capture date is in the last 2 months";
"Older" : "Capture date is NOT in the last 2 months AND capture date is in
the
last four months"

Now, using these two collections I can easily see what photos should be on
/Volumes/Mobile ("Older") and what should be on dropbox ("Recent").

So - is there any way to click on the "Recent" collection and this see the 12
or 120 pictures I've taken in the last two months and tell Lightroom to place
them in the "~/sandman/Dropbox/Pictures/year/month" folder without
selecting them manually?

I.e. I am looking for a "relocate" feature that takes metadata into account,
instead of selecting files and folders specifically.

Any ideas?
