Utilizing the Merge blueprint feature

Good day everyone, hope you are having a good day! Just reaching out to see if anyone else has had luck with utilizing the merge blueprint feature that seems to be in UE blueprints. Tried to use it, but the feature is not really explanatory nor is there documentation (at least that I can find). Trying to utilize it to help create a more seamless workflow with multiple people working on the same blueprint, without having to update everything manually, (time and cost consuming, but if need be will do it). If anyone has had success with merging blueprints, either in UE or with a separate program (i.e. source control [which reminds me, we are using Plastic SCM]) and have good tips or sites that helped, that would be greatly appreciated!

Have a good rest of your day!
