Another way of handling this would be to use the in environment expression:
in "environment-X": "find-Y" > "replace-with-Z"
And if necessary, you could go further and restrict that change to a specific book as well:
at 1KI in "\\io1 .+?\\ior": " ma in̰a Izrayel" > " ma\u2028in̰a Izrayel"
Note that you could also apply a custom-made character style to \sq squeeze the text \sq* that it finds if you think it might just all fit on one line with a bit of shrink/squeeze, for example:
at 1TH in "\\io1 .+?\\ior": "(ခရစ်ယာန် အကျင့်သီလ ဇာပိုင် ဖြစ်ရဖို့လည်းဆိုစာကို သွန်သင်ခြင်း)" > "\\sq \1\\sq*"
So, there are a few options available to you to adjust things when needed.
