You can attach any one of your saved Overview settings as the filter for D-scan. I’m not near a PC at the moment so can’t give the button by button details. This will be handwaving as a description. Sorry.
Now, since you probably want something different on D-scan compared to any of your Overview tabs the trick I use is to open a new overview tab, create the “what I want to see filter” in there, save it as something appropriate (“dscan” - I’m not original!), Then select that as the filter set in the D-scan window. Then I close thelat working overview tab.
Editing the list is a similar process.
All I tend to have in D-scan is all the capsuleer ships.
