Hello mmv, thank you for your comments. [. ..]

Noted, and agreed. If I could avoid this I would, but I'm resigned that the boat simply is what it is.

I’m with you on (a) and (b), but I’m trying to have (c) happen automatically-ish. In my own experience I find that manual procedures fall apart in spite of the very best of intentions.

Many thanks for your thoughts. It looks like nobody has anything further to add. I’ll report back if I learn anything more about the Sterling product.
