In writer, is it possible to save some frequently used “Find and Replace” items?

I often work with documents created via OCR and they often have fractions messed up, so I use “Find and Replace” to change them to whatever correct fraction is needed.

Is there a way to store them in the “Find and Replace” tool so they are always available?

If not, what other way can I easily process writer documents to find and replace these items?

Thanks
