replace tablature numbers with note names

It makes sense pedagogically. The advantage of tablature is that it shows exact fret positions. However, that is also its disadvantage. It doesn't encourage learning the note names on the fretboard and their relationship to each other. Adding the option in Musecore 3 to display note names in tablature would allow an intermediary step between tablature to standard notation, by still giving the suggested string (e.g., plucking hand position) without giving everything away.

From https://www.studybass.com/lessons/reading-music/alpha-tab/
"One of my biggest issues with bass tab has always been that notes are represented by fret numbers. Nothing could have less musical value to a developing musician than giving him or her arbitrary fret numbers to play. It would be like a painter trying to learn about using color and being instructed to use the 3rd paint can from the left. Other musicians all speak in the language of notes. If you say, "Did you want me to play a C# under that chord?", musicians will know what you're talking about. But if you say, "Did you want me to play the 4th fret?" only another bassist or guitarist will understand.

I still think reading standard notation is the way to go, but I don't think bass tab is useless.

Alpha Tab for Bass
My solution, which I have used for some time, is to use the note name instead of the fret number. I call it Alpha Tab. (Actually someone named it for me years ago on The Bottom Line mailing list.) This way the student is forced to think about the note names. Knowing the note names on the fretboard, and those that make up chords and scales, is extremely useful in your development as a bassist. You might notice I rarely describe things with fret numbers. It's for this very reason."

In the meantime, Richay VikaTa Daivata, if you are working in Musescore 2, consider experimenting with the "Add note name notehead plugin": https://musescore.org/en/project/add-note-name-noteheads
