How to resize tooltip in table?

Hello,

I am working with a report that uses a table as its primary visual. Most values are a short text string or number, but a few columns contain comments that may be a paragraph long. As such, I need to use a tooltip to be able to view the entire comment along with all of the other data. In most cases, this works just fine; however, on occasion more than one of these columns will contain a paragraph's worth of data, and the tooltip runs down off of my screen. I can't scroll through the tooltip, so it is impossible to view the entire amount of data for the row.

What I'm wondering is if there are any options for resizing (in my case, I would increase the width by an additional 100% at least) the tooltip popup. I've already tried reducing the text size down to 8 pt, but that doesn't quite do the job. Are there any options at all for increasing the amount of data displayed within a tooltip? I suspect I may need to submit an Idea for this problem.

Thanks!
