How to make a shared prefprops.txt file.

Hi,

When using the Edit Object Properties spreadsheet in Capture 16.6 I would like provide some new drop down filters to all users.
If I change the PrefPropPath variable in a local Capture.ini file to point to a central prefprops.txt file I find that this only works if
that file is writeable. If the file is readonly then it is ignored. This means that all users would be writing to the same file which
would not be a good idea.
Is there a better solution?

Thanks,
