After tinkering with VuhDo for a while, I read a short guide on how to make it show absorbs, and just found it incredibly useful for Disc. These settings will allow you to put an indicator on your party/raid frames in VuhDo, which will show the sum of all absorbs on that target.
This includes not only Clarity of Will, PWS, and Divine Aegis, but also abilities from other classes that are absorbs. (Ice Barrier, Anti-Magic Shell, etc)
So, without further ado:
1. Open up the control panel, and go to the "General" tab, then to the "Bouquets" tab down at the bottom-right corner.
2. Type in a name in the box labeled "...or a new bouquet name", and then click the "New" button to create your custom bouquet. (I used "absorbs counter" for a name)
3. Near the bottom-right of the Bouquet window, click the "Add" button.
4. Now, click the drop-down menu just below the name box, labeled "Select special event". In this list, choose "Counter: All Shield Absorb #k".
When you're finished, it should look like this:

Now that we've got our custom Bouquet created, it's time to position it on our raid/party panels.
5. Go to the "Panels" tab, and click the "HoT Icons" tab.
6. Use one of the drop-down menus to select which numbered slot you want the absorbs tracker to be positioned on.
When you're finished, it should look something like this:

That's all there is to it! Now VuhDo will have an indicator which shows the total sum of *ALL* absorbs on that target.
You can also adjust the size of the icon with the "Size" slider bar. You might have to do this, as IIRC, the icon starts off rather huge.
This is what it looks like:
A simple little icon with a number on it showing the sum of all absorbs on that target.
Hope this helps aspiring Disc priests be successful in their endeavors!
