PG should re-look into this old request which will add BIG value to BIAB's midi capabilities and markets, especially in China.
A big advantage of this Notation system is All tunes can be indexed and searched by their musical number pattern.
"An index using the numbered notation allows us to find a song if we remember the tune but not the name. To appreciate that, we can look at an example. A children's song book may have an index like this:
|1· 1· |1 23· | Row, row, row your boat
|1 1 5 5 |6 6 5 - | Twinkle, twinkle little star
|1 2 3 1 |1 2 3 1 | Frere Jacques"

Some Jazz standards can be found at
The Rousseau Music Book and read the original 1742 explanation of this notation systems by
