You might want to start by looking at ways to accomplish this with macros.

For example, it is possible to use an Action Button to replace an OPI with the
same OPI file and different macros values.  So I can have a row of buttons,
or one button with a menu, to select between different device instances.

I think it may also be possible for an embedded script to change macro values,
though cleverness with client side scripting is generally recommended as a last
resort.

wrt. generation screens.  So far I've only done this sort of thing offline.
eg. with python scripts to generate OPI screen files (variously .bob, .opi,
or .edl).  Usually with the idea of quickly generating tabular "expert"
screens for devices with a large number of scalar settings.

For cs-studio, this is mostly an exercise in xml.etree.ElementTree with
some logic to manage incrementing Y position for successive Embedded Display
widgets.
