Hello everyone! I have a question regarding the GitHub issue mentioned in this link: https://github.com/Netflix/metaflow/issues/245 My use case is as follows: We need to build a complex flow that satisfies various requirements. To illustrate, let's call this complicated flow "FLOW B". It comprises five steps, and it can either be activated manually or triggered within another flow that we'll refer to as "FLOW A". While we could manually duplicate and transfer flow logic, it would be quite tedious, and any modifications made to FLOW B would not be reflected in FLOW A whenever we "copy & paste" elements. Could you suggest an alternative method for composing and embedding flows within flows, where any updates or changes made in FLOW B would not require additional implementation in FLOW A? Thank you for your help, I really appreciate it!
