Chose to send or not to send sub items when automating items. And when sending sub items, include all columns

When creating an automation to move or create items in another board we need the option to decide if we want to include or not include the sub items in the automation. Currently the sub item is forced to move with the item and only 3 fields are included - Person, status and date.

The sub items are a task list. I do not need to share the task list with the next board. They have their own task list for the item.

In some cases I need to share the sub items. Works right? Except all of the columns arent supported. So If I fill out a large sub item column set and then automate to move the item to another board im actually losing most of the data because the unsupported columns dont go with the sub items.

This appears to be a year old request. Please fix soon!
