I installed Finale 25.2 30 day trial today and the first song I thought to try was Ave Marie by Chet Atkins which is using a DGDGBE string tuning.  So I made a new Tablature Staff Attribute and see it in the Instrument combo box in the Tablature Staff Attributes dialog.  I would like to create a new instrument to be listed in the Add Instrument that has this new Tablature Staff Attribute assigned to it but I don't see how to do that.  Where or how do I create an new Instrument that shows up in the Add Instrument button list?

What I am calling an instrument is in the ScoreManager dialog window, below the list of staff/instruments that are being used in the document that is a Add Instrument... button that opens a 3 column selection drop down.  First column is All, Common, etc.  The second column is type of instrument, I am selection Tablature, and then the third column list Guitar [TAB], Guitar [TAB - No Staff Name], etc.  I want to add a new option to the 3rd column called Guitar DGDGBE [Tab] which has my new Tablature Staff Attribute and Fretboard Instrument Definition assigned to it.
