Importing Score Writer and Overture files

Since Score Writer is essentially a subset of Overture, the file formats are very similar (or more likely identical?) - a minor change would allow Musescore to import Score Writer files.
I have tried renaming some Score Writer files, file extension .scw, with the Overture file extension .ove
Then Musescore will open these files, typically with no errors or only a few superficial errors. In particular, sometimes slurs from the original Score Writer file are not imported correctly.
Mostly, these errors are very easily corrected after a few moments work [I should, perhaps, qualify this by saying that I am normally working with rather simple scores of up to 3 staves so I cannot comment on behaviour with complex scores].

I suggest that Musescore should recognise the file extension .scw and should process it as equivalent to .ove
[Notes:
1. I am using Score Writer for Windows Version 4.1.0
2. I have posted a very similar comment to a topic in the 'Support & bug reports forum. I apologise if this duplication is regarded as undesirable crossposting.]
