I have a drop down custom field "ProjectGroup" and I have created a separate context for projects with some default value.
For Example: Context 1
Default Value = A
Projects : Project 1, Project2 , Project 3.
Context 2
Default Value = B
Projects: Project4, Project5 , Project6
Now If I move Project1 from Context1 to Context2 , I want custom field value of all existing issues of project 1 should get updated to B.
Is there any way to achieve this?
