How to Stop Folders from Turning on Syncing When Filing Messages?

I would like to know how I can keep my BB10 from turning on the 'sync' setting for folders when I file messages into those folders. I am using a Blackberry Z10, 10.1.0.4181, and have this problem with my corporate/Exchange email account that is sync'd via a Blackberry 10 enterprise server.

Here's a little more background on the issue:

• I have 1 or two folders that 'sync' to my Z10 (inbox being one of those)
• When I have read a message and want to file it in a folder, I select the overflow icon, select 'File' from the menu, and then select a folder
• The emails do get filed in that folder ... _however_, prior to me selecting the folder, that folder is not being synchronized to my Z10, but after I select the folder, suddenly that folder will begin synchronizing to my Z10 (the folder gets the little cicle of arrows on it identifying that it is being synchronized)
• This is a problem for me because some of the folders in which I file email messages are very large and I do not want them to be synchronized
• This problem did not occur for me when I was using my older Blackberry, so I am really hopeful that someone can help me understand what I have to do to make this stop happening

Thanks, Tyler

With 10.1 I don't think you can disable the folder sync when filing emails. 10.2 does have this feature, and a prompt pops up when you go to file the message. I haven't found if there is also a place to set this in the email settings.
