If you use File - Save As to save a single message, the message is saved with a name of [subject]

If you select multiple messages and use File - Save As, the messages are saved with names of [subject] YYYY-MM-DD hhmm

This may suit some people but not others. 

Could we have an option which allows the user to choose the file name pattern from any or all of the following:

Date/time in YYYY MM DD hh.mm format (so that it sorts chronologically)
Subject
From Name
From address
To Name
To address
  

Reproducible: Always

Steps to Reproduce:
1.Select multiple messages
2. File - Save As 
3. 
Actual Results:  
files named [subject] YYYY-MM-DD hhmm

Expected Results:  
Would like to be able to choose file naming pattern

Currently saving messages is inconsistent. For "SaveAs" this code

constructs a name made up of subject, sender and time/date. For drag&drop, only the subject is used:

As the reporter said, a facility to at least reorder the parts, like date first, would be useful.
