[Feature Request] Make keymap different based on the application name instead of class

[zw963]

Following output of wmctrl is a example.

the app in following example is a compare software, as you can see, based on different page(Text Compare/Folder Compare) in this app,
setting different keybinding is reasonable.

$: wmctrl -lx
0x03c00060  0 bcompare4.Bcompare4   lggram bottom-update - Text Compare - Beyond Compare

$: wmctrl -lx
0x03c00060  0 bcompare4.Bcompare4   lggram bin <--> sbin - Folder Compare - Beyond Compare

So, Can we different the Text Compare - Beyond Compare with Folder Compare - Beyond Compare use same rule as window class?

thank you.
