i think it is possible, but i've found it depends on the type of work going on (and how you approach it). i have a trauma history and i struggle in relationships as a result. different approaches would include:

1) looking at the past, to kind of 'heal' it (this is not something i have done in depth) and kind of free myself from my relationship baggage as a result
2) discussing "relationships" quite generally (this has been good for me, but i havent seen measurable change)
3) discussing a particular concern of mine regarding a current relationship and coming to a solution about that (this is the approach i prefer most -- it fixes my current problem, but gives me lessons for the future -- so i can make longlasting change also).

ive found if i try to prepare for what i want to talk about in session, i get more out of it also. i usually try to find 1-2 issues which can be fixed within a session, and then have another issue which we will continue to discuss over a number of sessions.
