Howto bulk edit / change all subtasks in BigPicture

[Ian Balas]

Hey guys, 

We're using the BigPicture add-on for our JIRA Software project to help manage task progress better.

I know there's a way to bulk sort all standard issues in a program by pressing the cog symbol and sorting A-z / Z-A from there. Is there a way to do the same for all the subtasks in all standard issues at once instead of clicking open and sorting subtasks for each individual issue nested with subtasks?

Any help would be appreciated.
