I have an interesting challenge. We have a project to handle a multi-year project to move applications into Amazon AWS. In this project there are master issues for each application and environment, and each master contains anywhere from 5 to 25 subtasks. Each of these subtasks has a specific ID type (let's call them A, B, C for purposes of this question). Our Director would like to be able to set an incrementing value for all of these ID-linked subtasks.
For example, master ticket FOO-1 has 6 subtasks, two of each ID type. They should be coded A-1, A-2, B-1, B-2, C-1, C-2. Master ticket FOO-2 has 5 subtasks, of types A and C. They should be A-3, A-4, A-5, C-3, C-4. Master ticket FOO-3 has 5 subtasks, all type B. They would be B-3 through B-7. And so forth.
What would be the easiest way to build something like this? Is it even possible?
