Hi,
I believe there is no such functionality available currently so this is a feature suggestion/request.
Coming from the world of programming I often miss the possibility to create some "function" to reuse in multiple places, and by that I don't mean to use in expressions, but rather a group of blocks that I can reference from other places, which can take parameters and eventually return values.
I am aware of the Subroutine block, and while it's possible to achieve a similar functionality using Subroutine + Go To + Label + setting correctly named variables, this approach is rather tedious, error prone and takes a lot of space, so it would be awesome if it could be simplified in some way.
Thanks for this awesome app and hope you'll consider this 😊
