Changing fingering on mandolin tablature

I play mandolin and managed to find adding tablature on one of your very helpful sites. I tried to find an answer to this particular problem, but have been unable to find an answer that I could understand.
If there is an answer somewhere that is easy to understand, please direct me to it.
My problem is rearranging the tablature fingering. For example, I would play a high E open on the first string, but I would like to play the same note instead on the second string, seventh fret, because I want to play other notes in that area. It would just be for two or three notes, so I don't want to change the whole tab settings.
