A big problem with the workflow you've described is that a sketched symbol
doesn't have any directly editable text. You can have text that gets its
value from an iProperty, which you've said you don't want. You can also
create prompted text entries in a symbol. Maybe this will do what you need.
When placing text in a sketched symbol you can define the text as prompted
text. When the sketched symbol is placed, a dialog pops up to allow the
end-user to define the text for each prompted text in the symbol. All other
text is defined by the symbol's definition and will be common amongst all
instance of the symbol.
I think the prompted text entries are close to what you want. It's possible
through the API to edit the values for prompted text entries but the dialog
will still pop-up whenever the end-user places one of them. I don't know of
a way to suppress the dialog for the Symbols command.
