Macroable Format / Hold Format Button

From what I can tell, there is no current way to use macros to set the live/blind channel display format to a known state, without using snapshots or other trickery. There is a "/eos/key/spreadsheet" command listed in the manual, but it seems to error out and have no effect. Being able to directly use macros to set display formats would be a much appreciated addition.

Additionally, the Format button could be tweaked to behave similarly to the Flexi button in live/blind channel display. For example, you could hold the Format button in Blind and select Spreadsheet from a popup menu or softkey to access Blind Spreadsheet.
