Description:
when using find/replace it could find targeted strings in cells and e.g. change background of those cells so they are easily identifiable.
Currently "replace" allows string-for-string replacement, general format change, no format change in "string-targeted" cells only, though.
(for review: such a feature is present in MS Excel)


Steps to Reproduce:
1. use Find/Replace and type in a string to search for in 'find' box
2. replace box should be left emtpty, but 'cell styles' should be chosen 
3. both find and replace boxes are affected, instead of 'replace' only, which renders the change impossible 

Actual Results:
no such feature

Expected Results:
ability to change format in cells with a given string


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
