Searching all Fast Formulas for a specific string of text

Content

Hi - we are looking to change the name of a legal entity and I would like to know if there is a way to search all the formula text of many many fast formulas to ascertain which may need to be updated, without having to go into each one individually?

Apologies if I have posted this in the wrong forum, or if I am missing something obvious!

Thanks in advance for any assistance

Linda
