I work in the IT Department at a company. Another department assigns tasks to our department for software support for a particular application that they use. We would like for them to rank the tasks that they want us to complete - with numbers - 1 through 25, for example. If they create a new task for our team and assign it as "1", we would like for the remaining tasks to then be renumbered as 2 through 26. If they create a new task and assign it as "3", we would like for tasks 1 and 2 to keep their assigned numbers and the previous 3 through 26 to get renumbered as 4 through 27. Could anyone please point me in the right direction for how to make this work?
