Is it possible to edit a sketch pattern to include new sketch geometry

Ie you have an existing sketch pattern of a square
Come back edit sketch and add an additional square within the original square ie offset, and have it be included into that same pattern instance and direction etc.

Yes and No.
The answer is yes if you feature pattern the sketch. No if you use sketch pattern in the sketch.
More effective to pattern the feature than the sketch if it gets the results you want.

Sketch patterns are less efficient (don't know why but that's the way it is). The problem with feature patterns is it's harder to align stuff, for example if you want the pattern centered between two faces. Maybe there's a better way to do this but at the moment the only way I know is to type in a formula to calculate the exact pattern distance mathematically. Using sketch, I can create the pattern, delete the distance dimension and then align patterned geometry to existing geometry using sketch constrains, which is more intuitive and a lot easier.
@MannyF:
Perhaps you could use the sketch geometry (perhaps with pattern) just to create construction geometry. use a measured variable (e.g. on a line length) to drive the feature pattern. that way you will use the ease of definition of the sketch (i.s.o. formula's) and combine it with the flexibility of a feature pattern.
