This may not be possible. But, how do you take adjoining polygons, merge them together, but still keep the diving lines (in case you want to dissolve or explode it later)?
This is what I have:
![](/legacyfs/online/461096_pastedImage_1.png)
Those selected ones are four separate polygons. I want to make them into a multipart feature without losing the middle lines. Is this possible?
