Is it possible to resize dialogs while linguists are working on translations with the Collaboration license?

Hi all! 

Is it possible to resize dialogs while linguists are working on translations with the Collaboration license?  I had hoped to set up my work so that we only exchanged tbtrans/tbupd files over the course of the project, but it seems as if I can only edit source files.  We have a lot of dialogs that I (as PM) normally resize since this is expensive work to outsource.  But it seems as if I'll need to unexport the tbulic files to edit the target content.  Would also be helpful to be able to fix bugs, but this also involves write access to the target files....I had hoped that I could set up a process where I just cycled between receiving tbtrans and posted tbupd files, without having to also manage the tbulic files.

Thanks!
