Bulk insert

[evanjmg]

1. Describe a problem.
   I have dozens of elements that need to be deleted then reinserted and replaced (i.e undo a particular section of document)
   elements.forEach((el, index) => {
   this.editor.blocks.insert(
   el.type,
   el.data,
   {},
   })
   Right now, the performance takes seconds for a render to reoccur after this insert.
2. Describe the solution you'd like. Mockups are welcome.
   I'd like a insertMany([...], { startIndex: 10 }) option that would not have a significant performance improvement (hopefully).
3. Are there any alternatives?
   Only way around this is doing less inserts - In my case I have a 1000 blocks in my document.
