Suppose Jira JQL filters named Filter1, Filter2, and Filter3 with a reasonably complex JQL each of them.
I need to create a new one named BigFilter as being: Filter1 OR Filter2 OR Filter3.
I do not want to merely rewrite the JQL from the other filters again in BigFilter. I want to take advantage of the already existing JQL in the initial filters.
How can it be done?
