Lee D,
On the mac side I looked at /Applications/Canon Utilities/Print Studio Pro/Plug-in Install.app <I showed contents> and found Contents/Resources/Plug-In Install.plist
Although not a programmer but hacintosh user I wonder if adding to the plist for Affinity Photo would work. Here is just a snippet.
<key>PSAppList</key>
<array>
<dict>
<key>DispName</key>
<string>Adobe Photoshop</string>--changing to Affinity Photo
<key>AppName</key>
<string>Adobe Photoshop CS4</string>--changing Affinity Photo.app
<key>ProcName</key>
<string>Adobe Photoshop CS4</string>
<key>PathName</key>
<string>Adobe Photoshop CS4 Paths</string>
<key>PlugInType</key>
<integer>0</integer>
</dict>
Naturally you would need a copy of Print Studio Pro in case you brick it.
