Edit Existing Tooltip

[Rhyono]

Is there a function that allows you to universally hook into a tooltip by name? For practice purposes, I used Zgoo to look at the data of the alchemy tooltip that pops up when you have a solvent and reagents placed. I see that the functions AddLine and ClearLines can be used to modify it, but how would I go about calling those from outside of Zgoo to modify it myself?
