Christopher, I asked about this issue in early 2019 when the Sky group was still on Yahoo. I assume you're doing work for McFarland, as I was. Deborah Patton kindly replied to my 2019 post, and I ended up using her approach with minor modifications. I use Sky 7, but this should work for v.8 as well. Here's what Deborah wrote:

I don't see a clear way to
do it (I'm using Sky 8) so I think what you want is a way to find the subentry
records. Set your locator leader to two spaces, but then I'd index as
usual. At the end you can Find all the subentries (Find * in the sub1
field and group the result) and with them grouped you can add a character
(maybe a ^ or something ) before the locators for that entire group.
Generate the index. [MY NOTE: I used an @ symbol rather than a caret ^ since the latter has special significance in Word searches.]
When you get to Word, you can find all instances of two spaces and that
character and replace with one space. Be careful with replacing them all
at once. Or try it on a small subsection to find out what happens

This approach worked great for me. I can send you a screenshot of the pattern matching that I used in Sky to insert the @ symbol at the end of all subs.
HTH,
