footnotes that ref the page it occured on

hi, i’m writing a non scholarly manuscript. i have a bunch of footnotes, for example:

example 1:

The fish swim up stream to spawn.

example 2:

The “fish swim” up stream to spawn.

in the two examples, the only difference is the " " around fish swim. i would like to 1) put the “fish swim” in a note at the end of the manuscript referencing Johnson 1989 and 2) and also insert the full citation in the bibliography.

so, if the note occured on say pag 17, then the note would look like:

  1. “fish swim…” Johnson 1989

the 17 would indicate the note appeared on page 17 in the manuscript and the bib would appear

Johnson, JD 1989. The activities of fish. Journal of Fish Stuff, Vol 1 etc etc

anyone have any idea how to do this? importantly, can i highlight the text in th ms. and start the process?
