It's similar but maybe slightly different. At least with bass guitar, the different positions you can play the notes will end up with the notes sounding slightly differently even if it's the same fundamental frequency (particularly open strings sound dramatically different, but even outside of that each string has its own sound). Also there might be a consideration about how the transition between two notes sounds which could be affected by whether the 2nd note is played on the same string or a different string than the first. I expect most (if not all) of these concerns would apply to any stringed instrument where the length of the string changes. It's not something a beginner would need to worry about generally but that might be why such a thing doesn't exist already - the pros all have their own unique methods for determining fingerings.
