Ability to Automate Mirrored Columns

We use setup w/ a Master board like a data bucket & numerous boards feeding off of it w/ a variety of mirrored columns. This works well, but has several limitations. It would be a massive improvement to be able to automate the mirrored columns. Is this possible, and/or on the development list?

For example, when the project status column is moved to done in the Master board it moves the item to a Completed group. Unfortunately, we need to manually move the item on each board where it is mirrored separately. With automation on the mirrored status column we could set it on each board to move to the correct group to save the inefficiency of manually moving it.
