Using setAndSave() with subfields

[Robin S]

Some fieldtypes have 'subfields' (not sure if that's the right term exactly). For example, the "Address" field within the Map Marker fieldtype.

Is it possible to use setAndSave() to set some subfield of a field? Seems like it should be possible but I can't work out what the right syntax is.

Hmm...I don't think it's possible. But you never know!

Is it possible to do this now? Say, for example, I want to save a FieldsetPage doing something like:

$page->setAndSave('button.url_address', $value);

EDIT: I think it's not, just reviewed the Page class ?
