This only appears to happen when I click on the face of an inserted part.
Right-click on the selected face, go to Parent/Child...
In the Parent Child Relationships dialog box, expand the features to reveal the absorbed sketches
Select each sketch, right-click on it and select 'hide' from the context menu.
There isn't a more elegant solution than this at present. You should submit and enhancement request through the customer portal for this kind of functionality.
Many thanks! I will pass this on.
