Is your feature request related to a problem? Please describe.
Currently you can only access tooltip1-3 without custom code. On Sarkareth there is a debuff called Void Claws where the important part would be tooltip4.

Describe the solution you'd like
Add at least %tooltip4 or even more (probably unncessary).

Describe alternatives you've considered
I've writtem some custom code that uses WeakAuras.GetAuraInstanceTooltipInfo and WeakAuras.GetAuraTooltipInfo because the function Private.ParseTooltipText seems to return all the tooltip values.

Additional context
If you need additional context just reply to this feature request.

If you want to have that implemented fast, you need to provide a PR.

The alternative works fine for me. I just thought that it could be useful in the future.
