Is there an EPICS version where I can write (via link, DB or CA) a
scalar to one specific element (i.e. index) of an array field? I am not
as up to date on EPICS development as I used to be, so perhaps this has
been added and I missed it, perhaps in 7.x (hope dies last...).

Filters on write (that would be the obvious way to do it) have not been implemented yet.
Dirk Zimoch added filters for DB links at the last Codeathon, but - as with CA - these are only working for get and monitor; there's nothing (yet) for the write operations.

Pull Requests / Merge Proposals are always welcome!
(And thanks again to everyone who attended the recent Codeathon - that was a very productive week!)

Cheers,
