How to add multiple values to a single field ("stack" behavior)

[Edgar Oregel]

We're running Jira server 8.4.1, and we've been looking to find a solution for the issue below:

- We have a team that is tracking percent complete (planned and actual) for every task, every WW in the year. This could be solved if we had a field that we could add more than one value, essentially append a value to that field, and have that field store a "stack"/history of all the values that have been added. 

Is there a plugin that exists that can accomplish this? In general we're looking for a plugin or resource that has custom fields that act like "stacks" or an "array" where you keep appending values to that field.

Hi Edgar

I don't fully understand in which way you want to use this field, but if you need a field, which shows the data history of another field, you can do it with the Scriptrunner Plugin.

You would create a custom text field "History of Field A" which is appended with the current value of field "A" as soon as field "A" changes (on change listener).

The values could be comma-separated, for instance, or whatever format suits you the best for your analysis.
