I tried adding 'pageprefixsegments' to setupregister, but cannot find any value that adds anything, ex. pageprefixsegments={WB1}
pageprefixsegments=part:number

How does it work? I'd be fine if the index listed pages like "WB1 3" meaning "Workbook 1, page 3", it isn't ideal but is better than not having the index showing anything.

In this case, you could use \part per workbook and use 
pageprefixsegments in \setupregister to add the part number in front of 
the page number.

Otherwise, I guess it would be possible to read the .tuc files of the 
other products to create index entries. (Some Lua programming; shouldn’t 
bee too hard, but still way over my head.)
