Hello @dec, thank you for the post @mark’s suggestions are excellent, I completely agree.
I do believe opening a separate topic is a bit redundant, since I’ve replied to your question regarding the same thing in a different thread in quite a bit of detail. Here is a link for your convenience:
I believe the “How to rename a collection” topic has been explained pretty well and, as such, resolved, so I’m going to close this topic
Hope this helps,
