Is it possible to copy many blocks at a one time or create many similar blocks at a one time?

I need to create a huge amount of similar blocks, but the problem is that to create them one by one incredibly long, is there a plugin or something that allows you to either create a lot of identical blocks that are different only the name and texture, or to create sets of blocks like set of wood? Attempts to copy blocks manually also failed, Mcreator says that they are corrupted, a guide how to properly copy them manually I also did not find. Are there any solutions for my problem?
