Precomputed Indexes

This is pretty much a repeat of this question: https://intellij-support.jetbrains.com/hc/en-us/community/posts/206977835-Can-intellij-s-indexer-be-invoked-from-the-command-line-in-batch-mode-?input_string=Precomputed%20Indexes

Given it was asked more than 10 years ago I thought I'll resurface it.

In short, I'd like to build the indexes once and then distribute them instead of everyone recomputing them. IntelliJ indexing is one of largest time drains in the local development workflow so improving this would be great.
