How to quickly add stuff (abbreviations, etc.) to segmentation rules when translating?

OK, in memoQ, when you run into an incorrectly segmented segment caused by e.g. an abbreviation, you can quickly add it to your segmentation rules for the current src language, and even re-segment your entire project (if you want). E.g., I just ran into this problem, as Studio segmented on "FIG.", I don;t want it to do this. How can I quickly tell Studio not to break on "FIG."?
