We had similar problem when we tarted to construct KEKB
control system. So we developed a new record called Compact
Subarray record. It just copys amount it needs from a source
record. We need to add new API in dbaccess library, which is
not present in the standard EPICS base, to support this record.
If you have an interest on this record, I will be happy to
send source code.

Thank you for the thought.  I'll see if I can make things work with
subArray first.  If I have problems I'll be in touch!
I'd prefer to use the standard record type (even if I am milding
abusing it) if I can.  You say also that your Compact Subarray
"copies amount it needs from a source record" -- do you mean that the
source has to be another Epics record, or can it be purely device
data?

Currently it just have SoftDevice support. In priciple, you can use
write device support for this record.
