Bulk copy of plans

Hello,

Is there any way to copy all the plans from one project to another? I have seen that our users can copy plans one at a time, but this can quickly become tedious in our environment. I noticed that there was an old add-in that seems to have done this, but it is no longer compatible with the newest version.

Currently we have a handful of users who are spending a lot more time than they should copying plans between multiple projects and environments.

Thank you!
