Job dependency on some members only

For the CAMS2-40 workflow, we need to run a synchronized job (DA) that only depend on some members. You can see an example of the workflow in a3wo, but a simplified version looks like this:

    graph TD;
      a3wo_20210802_000_1_SIM-->a3wo_20210802_1_DA
      a3wo_20210802_001_1_SIM-->a3wo_20210802_1_DA
      a3wo_20210802_002_1_SIM-->a3wo_20210802_1_DA
      a3wo_20210802_003_1_SIM-->a3wo_20210802_1_DA
      a3wo_20210802_000_1_SIM-->a3wo_20210802_003_REDUCE
      a3wo_20210802_001_1_SIM-->a3wo_20210802_003_REDUCE
      a3wo_20210802_002_1_SIM-->a3wo_20210802_003_REDUCE
      a3wo_20210802_003_1_SIM-->a3wo_20210802_003_REDUCE
      a3wo_20210802_1_DA-->a3wo_20210802_1_REDUCE_AN

with

[SIM]
RUNNING = chunk

[DA]
RUNNING = chunk
SYNCHRONIZE = member

[REDUCE]
RUNNING = member
FREQUENCY = 4

[REDUCE_AN]
RUNNING = chunk
SYNCHRONIZE = member

The idea is to have something like this:

    graph TD;
      a3wo_20210802_000_1_SIM-->a3wo_20210802_1_DA
      a3wo_20210802_001_1_SIM-->a3wo_20210802_1_DA
      a3wo_20210802_002_1_SIM-->a3wo_20210802_1_DA
      a3wo_20210802_003_1_SIM-->a3wo_20210802_003_1_REDUCE
      a3wo_20210802_1_DA-->a3wo_20210802_1_REDUCE_AN

so

1. the DA job should depend only on 00[0-2]SIM
2. the REDUCE job should run per chunk, only after x member (I need only reduce_003), and depending only on a3wo_20210802_003_1_SIM.

Could this be done in Autosubmit?

(I know, workflows with DA are always a challenge 😅 )
