VMAX Initiator Group Port Flag Overrides

I'm trying to get a global view of all flag overrides without having to crawl every IG and output one by one in a loop (very slow if many IG's).

With  symaccess list view -detail -sid XXXX  this shows every Masking View, and additionally shows every child initiator group, so if we have

MV_cluster    with sub child initiator groups  IGC_server1 and IGC_server2, then list view -detail will show *3* full entries

1 - the full MV with child groups listed in the IG section

2 - again, the full MV, this time with IGC_server1 actual WWN's listed in the IG section

3 - again, the full MV, this time with IGC_server2 actual WWN's listed in the IG section

So this is great, and I can get all information pertaining to all Masking Views into an output file, or output to XML and parse later.

But, the problem is that I need to collect all port flag overrides information for all IG's, which can be done via the specific command for that IG as below. What I would like is a full listing that shows every flag override for every WWN in every IG. Commands like list view -detail, suggest that this should be possible (obviously I can run a loop to run all of these commands, and I could do that to collect Masking View info also, but that's *hugely* slower than the list view -detail to get everything in one sweep). Would appreciate if anyone has a way to collect this info efficiently (parts in red are specifically what I am interested in collecting globally for an array - maybe some long format XML output includes this that someone knows as sometimes that outputs different information from the non-XML output?)? Thanks.
