Searching not using exact task name.

I have 100-300 subtasks per group that I use a dependency on the same subtask from the previous group. A lot of them start with the same coding but the ending is different. I would like to be able to search for the ending of a task and not just by the start, or typing out the same task verbatim. For example if I have a subtask 6MMPWIS50BCTL#17 I would love to be able to search just #17 from the dependency search screen, instead of 6MMPWIS… because the only difference between that code and the 10 others like it is the number at the end.
