How to use the same executor multiple times in flow

Describe your proposal/problem I am using multiple local executors. One of them is LMDB. I would like to access LMDB twice in my flow, but without running two executors but just one. (to save RAM).

- name: chunk_match_db_filler
  uses:
    jtype: LMDBStorage
    py_modules:
      - executors/lmdb_storage.py
  uses-with:
    default_traversal_paths: ['cm']

- name: ranker
  uses:
    jtype: IRanker
    py_modules:
      - executors/ranker.py
  uses-with:
    dim: 768

- name: root_match_db_filler
  uses:
    jtype: LMDBStorage
    py_modules:
      - executors/lmdb_storage.py
  uses-with:
    default_traversal_paths: ['rm']

It will spin two lmdb_storage.py executors on different ports.
