Lawyers can and do choose which cases will be set for precedent all the time. It's somewhat difficult to ensure that your case is the only one going after the said precedent at the right time, but just about any time a new law is passed that people object to, lawyers begin shopping for ideal candidates and then determining the best ways for them to break the law in the least damaging way, and in the best possible district to get the law deemed unconstitutional. This typically happens with civil rights cases, and it's worth noting that there are certain legal groups that are better at it than others -- the Second Amendment Foundation is exceptional, and it's a large part of why their win record is so good.
