To be generic, such a feature would have to work cross-IOC. (As the application has no control over the servers that a set of PVs is deployed to.)

Which makes this feature a typical middle-layer issue.
PVManager [1,2] is targeted to achieve a similar thing for V3 and V4 (as a client library), the Gather service will provide combining different PVs into an array for V4 (as a middle-layer service).

Cheers,
Ralph

That's an idea but requires a lot of bookkeeping by the application
for supporting something that could be of broader interest.

I could imagine EPICS' subscription mechanism being enhanced with
a feature that lets you subscribe to a set of PVs and then
be notified when all members of the set have updated.

FWIW
