Hi Pedro,
The capability to refresh the plan is already available in the LifeTime September CP1 release. So you can now add updates from source environment (like new tags or application changes) into your plan without discarding it and creating it again.
Although you don't need to recreate the plan again you still need to fix/refresh the outdated dependencies first. That part I would say that is related to this idea: https://www.outsystems.com/ideas/159/auto-refresh-espaces
Let me know if I'm covering the full picture.
Thank you
