I had a similar project. Complex walls is probably the best solution if you have several walls the same, but the quick work around I used was to create 100/102mm wide beams with a material strength greater than the general brick and place them in the wall. This would be more suited if the strings aren't continuous e.g. brick sills or feature courses in limited locations. Using a beam should also avoid AC trying to resolve wall intersections.
Let us know how you get on so others can learn from your experience.
