[Libreoffice] Replacement table enhancement for Braille table

Hi all,

A French user is currently working on a project to get an abbreviated 
braille table implemented in LibreOffice (in French).

We have determined that the replacement table could do a very good job 
here for single replacement 1 to 1 with a determined pattern.
For example : b=but c=can, [$c=because of, 7=tall, etc...

Now would it be possible to enhance the replacement table so that we can 
execute the pattern *oe* to be replaced by the pattern *oeu* in each 
word containing this first pattern, that could be at the beginning of 
the word like in oeuf or in the middle like in boeuf.

The same for the end of a word containing the pattern *ait at the end, 
only entering 3 will replace the *ait at the end of the word.
Of course, we could use the search/replace function at the end, but it's 
a very different use than entering your whole text using the braille 
keyboard.

Thanks in advance for you evaluation
Kind regards
Sophie
