is it possible to copy/merge specific file/s from Transactions to current branch?

Hi    SmartSVN:6.6.12    I am trying to merge some staff from a trunk to branch. The key word here is some. I am not looking to merge full revision.  I use Transactions window to see what was changed in a trunk and by whom. So i would expect to have functionality where you can select file/files you see in transactions of a trunk (or different branches) and would be able to move it (or merge) to current branch. Unfortunately i can not achieve it.    Can you please suggest how can i make this working in SmartSVN and if this is possible to do at all there?    thanks in advance!
