How to replace text with font style/color "italic red" to one of my created Character Styles?

[BrentGG]

[LO Writer 7.4.7.2 Win64]
I wrote a long ODT document and used Italic Red font attribute to mark up some of the text. Since then I switched the document to using character styles which works great! However I now need to replace the old Italic Red font attributes applied to some of the text over to the new Character Style. Is this possible? If not, it will take me days to do it manually.

TIA

1. Edit>Find & Replace
2. Click Format
   • In Font tab, select Style: Italic
   • in Font Effects (if this is character colour) or Highlighting (if this is background colour), select your colour from the palette
3. Find All in the main F&R dialog
   This will select all occurrences. Check anyway there are no false-positives.
4. You can close the F&R dialog or push the window aside
5. Doubl"-click on your character style in the side style pane
6. Ctl+M to clear your coloured direct formatting

You can now click anywhere to cancel the multiple selection created by F&R.

Caution: F&R seems to be very picky about formatting attributes selection. You may need several attempts to get it right.

0. Create the desired character style. Use the Parent: “No character style” option when you want modify only that two parameters but not the other parameters of the applied paragraph style.
