- I have built a custom field multi checkbox plugin.
- I have extended the class MultiSelectCFType
- Using the Change History manager, i have written a logic to fetch the details of signed date,time and username.
- I'm just printing it in the UI(edit.vm and view.vm).(Not storing it in the database)
- I have attached the screenshot as well. kindly take a look

Issue:
- I want to do JQL search for the multi check box field with the signed off username. JQL Query smaple: "signoff_1 = pshenbagadelip"
- Is it possible to store the Signed off username and date to the DB?
- Is atlassian supports saving additional values to the custom field? or is there any workaround?
- If so, then it will be easy to do JQL search without affecting the performance of the JIRA.
