Can i do one of the following? (if yes how?)
- save about five "search and replace"s. then do them all at once to any ebook later (- preferred).
- do one "search and replace" on many ebooks at once. (- not preferred, I'm worried it will take forever, or calibre will stop responding.)
- add saved "search and replace"s to my default import preferences so they will be dune automaticy, or upon choosing a option. (i'd prefer this, if it's not to complicating.)

in advance.
