The latest version seems to be buggy and not working.
However, since older versions have a very complicated data structure, it is quite hard to support this.
The data is not a simple table, but a pointer is sandwiched between them.
It is difficult to express such a structure on the patch screen.
It is possible, of course, if you implement using C# on the FEBuilderGBA main ...
I think that it is not preferable to design a screen newly for one patch.
