Moving existing collections into Publish Services

Hello, 
because I cannot find the solution or discussion to this topic, I guess it would be good idea to implement in next update. (I'll be happy if Im wrong and somebody will help me with that, thank you)

ISSUE:
IS IT POSSIBLE TO DRAG/MOVE EXISTING COLLECTION SET INTO PUBLISHING SERVICE? (So the pictures would export into folder structure of "colleciton set / colection 1, 2, ..." )
Since I already invested lot of time into creating collections I wouldnt need to do same work again in publish services?

description:
I created collection set with many sub-collections (architecture / specific buildings).
I would love to publish this keeping the hirearchy so the lightroom would create folder "Architecture" and inside of it separate folders "building 1" "building 2" and so on.

POSSIBLE FUTURE SOLUTION:
I would imagine that there should not be big problem just draggin existing collection/collection set from collection menu into one of created publish services. Then when I would publish the set the corresponding folder structure with photos in each would be created and exported.

BENEFIT / VALUE
Saving time - no duplicite work needed.
Easier organization of exported files as result.

Does it exist? Or am I missing something? When I drag it it does not add any pictures/collections into pop-up menu.

Thank you so much for your help/reply/ideas and time. I really appreciate it.
