Schenkerian graphing options for future Notion updates

Dear Madam/Sir:

As a regular user of Notion for generating exercises for my students, I would be very interested in having the ability to generate Schenkerian graphs using the software. These would include options, such as but not limited to:

• unstemmed notes of different time value
• various types of ties as utilized by Schenker (i.e., solid, dashed -- over, under)
• larger beaming of notes together over multiple measures to identify the fundamental structure
• ability to remove bar lines
• inter-clef beaming of structurally or non-structurally related notes horizontally
• degrees of scale notation with carets
• functional chord notation (Roman numerals)
• harmonic interval notation

Here are two examples of many such symbols:

An ability to export them as JPEGs would be similarly useful. Combined with approaches to "structural hearing," I find Schenkerian analysis a useful pedagogical tool.

Your help in this matter would be very much appreciated. Short of very laborious approaches with Finale or Sibelius or having to learn LilyPond coding (begun but glitchy with a Windows rather than Linux platform), there does not seem to be any other options which I have found to date.

Yours sincerely,

Andrew Waldie.
