Short question: if you have multiple trees on Ancestry.com is there a way to set one to be the default tree?

Longer description of my problem: My principal tree on Ancestry.com was the only one I had until yesterday, when I added two additional private trees which I intend to update rarely. When I logon now Ancestry seems to remember the last tree I was working on, so it is offering my principal tree just as I would want.

While working in my principal tree Ancestry Hints have found other public trees and when I look inside these trees there is data I would like to add to my own. However whenever I hit the "Save this person to your tree" to copy this data to my principal tree Ancestry offers up instead one of my new trees, not the tree in which I have been working.

I have to hit a down arrow, wait a bit, then reselect my orginal tree, wait a bit, then finally get to continue. These extra steps are very annoying time consumers, which would be unnecessary if there is a way to set my original tree as the default.

Grateful if anyone has a technical suggestion. Keying the data in manually because it is more professional is not why I subscribed to a website with automated features :o) Thanks.
