The Sibelius Sounds library which ships with Sibelius 7 and later does not have support for reduced player configurations such as a2, a3, a4 etc., but if you are a NotePerformer user, you are in luck.
NotePerformer 3 installs a plugin in Sibelius called “NotePerformer a2, a3 … MIDI message” which appears in the Plug-ins page of the home tab.
This plugin adds a MIDI controller message to a beat, or the start of a selected region for playback when using NotePerformer.
In other words, you can apply this plugin to add hidden MIDI controller info at the same location as the “a2” text, so that NotePerformer produces correct playback of a2 etc.
You can use the plugin to add this MIDI Controller data each time, or you can also add this controller info directly in your score either manually or automatically with NotePerformer.

Harp pedal diagrams in Sibelius can be entered using several methods. For instance, as shown in this blog post, you can manually enter a harp pedal diagram using 4 regular text characters (LMNO), then change the font to Opus Text.
There are also a growing number of harp support plugins for Sibelius to automate the process of creating harp pedaling notation (and playback), as outlined in this article by Bob Zawalich on the Sibeliusblog.

Q: Is it possible to make title text appear more “expanded” (as I might do in a Word doc?) My client has a specific font request, but his letter spacing looks wider than the same font on my computer, which is more “tight”: A: This difference is due to letter-spacing, referred to as “Tracking” in typography. Tracking refers to a consistent degree of increase (or sometimes decrease) of space between letters to affect density in a line or block of text. more >> “Adjusting Tracking, aka Letter-Spacing in Finale & Sibelius”
