Updating not actual branch

Hi All,

I have a question if there is a posibility tu update a branch which is not
actual working copy.

I have following situation:

A - B - C - I - J                       master
               \ - D - E - F               feature 1
                                 \ G - H     feature 2 (working copy)

I would like tu update whole tree with latest changes in master

A - B - C - I - J                                              master
                           \ - D* - E* - F*                  feature 1
                                                   \ G* - H*     feature 2
(working copy)


Is there some way how to do it without swithing to each branch and update
them manually?

Thanks,
Jan
