Unset Complete Array on Condition

Much like we can already unset a field on condition NULL or is EMPTY it would be great if we could unset a complete line.

For example
items.*.sku = empty -> unset items.* (just the current line).

Added Bonus:
Add a meta field for 'lines unset' with a boolean or something along those lines so a route can be used directly after to a notify shape that a line was unset due to a null condition being met.
