AutoCAD Inventor :: Healing Chain Centerline That Has Broken / 2012

how to heal a chained centreline between a row of hole features?

Here is my current work practice...

I have a panel with a row of hole features, they are not an array as the pitch between holes typically varies.

I create a chain of centres along the row.

I copy the panel and drawing to make a similar part but I remove one of the holes from the middle of the row.

Now the chain centreline is broken, obviously missing a feature and I cannot find a way to heal the centreline unless I delete and recreate it.

There is also the switcharound too where I add a hole within the row.I typically have to do this for nearly 60 similar panels.
