Imploding voices with lyrics into one staff, but having the lyrics stacked vertically?

Hi folks, 7 years ago I wrote some singing scores for a musical, ranging from one to five staves with lyrics. I'm now writing the piano scores, and want to implode the singing scores with lyrics all into one staff for ease for the piano player, so that they just have one singing staff to look at rather than two, three, or five. I've included an excerpt of one piece in example one pdf. below, 'original'

Trouble I'm running into: the implode function is working fine for the notes themselves (even if it's sometimes a bit messy); however, since when I first wrote this I put all the lyrics on the first line below the staves, the lyrics also get imploded all onto the same (1st) line, and are very hard to read--see example 2 pdf. below, 'imploded all on one line'

I'm looking for an expedient way that when I implode the staves with lyrics, they are stacked--see example 3 pdf. below 'result I'm hoping for.' However, I was only able to get that (example 3) by rewriting -each syllable- of the lyrics for each stave on the 2nd or 3rd line, then deleting those lyrics from the 1st line.

Seeing if anyone knows if there's a direct way to ideally take all the lyrics in one staff before I implode them and take them down one line, so that when I implode they'll be stacked. I've tried highlighting all the lyrics in a stave, but haven't found a way to bring them down yet. Admittedly pessimistic that Musescore would have this esoteric a function, but hopeful in case it's out there, as it would save me hours and hours of work.

Thanks for any tips! FYI I'm still using Musescore 3 [don't know which exact version of 3]
