`Mass Quote` (`i`) requires `Cancel On Disconnect` enabled and MMP.

Request example:

```
MassQuote
 QuoteID="MyQuote1"
 9019="default"
   NoQuote_sets=1
     QuoteSetID=1
     TotNoQuoteEntries=2
     NoQuoteEntries=2
	 QuoteEntry_id=1
     Symbol="BTC-PERPETUAL"
     BidPx=41000.0
     OfferPx=42000.0
     BidSize=10.0
     OfferSize=10.0
	 QuoteEntryID=2
     Symbol="BTC-29DEC23"
     BidPx=41500.0
     BidSize=5.0
```

In reply to `Mass Quote` (`i`), the server sends  `Mass Quote Acknowledgement` (`b`) message as well as corresponding `Execution Report`-s (`8`). The reports and acknowledgement are send asynchronously and via different queues, so the precedence of acknowledgement message is not guaranteed.
