I know this is something that has been raise before (such as issue #212), however the last I can see of it is this response in 2017 . I was wondering if there was any update on multiblock patterns, be it still in the works or unfeasible.

I have a large window design, which I need 15 patterns to copy. This is a design I really like, and would like to include quite a few times throughout my builds, however the work to do so currently makes it quite a daunting task. (As an aside, if it were possible to mirror and rotate patterns (like you can chiseled blocks) the number of patterns would be reduced to 9, although this is a separate issue.)
