Kanban Board filter to filter by priority then children ticket priority

[Dylan Silva]

I am having a hard time thinking of a filter that will rank first by priority desc then by their child tickets priority. For instance

If the parent ticket has a priority of P1, but the children tickets have varying priorities within it, then the children do no remain "attached" to the parent ticket.

Here is my current filter:

project = MyProject AND NOT issuetype = "IssuetypeA" AND NOT issuetype = "IssueTypeB" ORDER BY Priority DESC

You may want to take a look at this plugin. It has a subtask JQL function (https://marketplace.atlassian.com/plugins/com.j-tricks.jql-plugin)
