Control footnote column width and placement?

Hello,

My client used dynamic footnotes, which I find frustrating to deal with.

I have a 3-column layout (see attached image) and the footnotes are falling in the column in which the

reference shows up. But I want to have footnotes preferably always fall in the leftmost column

and stretch across at least 2 columns. I feel like I've done this before but don't recall how I controlled them.

Is there any way to do this?

Also, the footnotes seem to be in sort of table-like cells. If I turn on "show frame edges,"

I see blue lines surrounding each footnote. I have paragraph style set to 1p above but that only refers

to the entire block of footnotes. How can I add space between each footnote?

Thank you,

Jane
