take a look at the starting number on the pattern. what I actually typed is 8091003, but it seems to be adding commas and once it adds a comma messes up the typing.
also, lets say I have devices 8091003, 8091008, 8091012. If I try and do a pattern starting on 8091003 with a length of 3 it adds 8091003, 8091004, and 8091005. Shouldnt it maybe check and make sure that those actually exist before adding them? That may not be an actual problem, but more of a feature request.
